| |
| == Spring Boot Auto-Configuration |
| |
| When using vertx-kafka with Spring Boot make sure to use the following Maven dependency to have support for auto configuration: |
| |
| [source,xml] |
| ---- |
| <dependency> |
| <groupId>org.apache.camel.springboot</groupId> |
| <artifactId>camel-vertx-kafka-starter</artifactId> |
| <version>x.x.x</version> |
| <!-- use the same version as your Camel core version --> |
| </dependency> |
| ---- |
| |
| |
| The component supports 99 options, which are listed below. |
| |
| |
| |
| [width="100%",cols="2,5,^1,2",options="header"] |
| |=== |
| | Name | Description | Default | Type |
| | *camel.component.vertx-kafka.acks* | The number of acknowledgments the producer requires the leader to have received before considering a request complete. This controls the durability of records that are sent. The following settings are allowed: acks=0 If set to zero then the producer will not wait for any acknowledgment from the server at all. The record will be immediately added to the socket buffer and considered sent. No guarantee can be made that the server has received the record in this case, and the retries configuration will not take effect (as the client won't generally know of any failures). The offset given back for each record will always be set to -1. acks=1 This will mean the leader will write the record to its local log but will respond without awaiting full acknowledgement from all followers. In this case should the leader fail immediately after acknowledging the record but before the followers have replicated it then the record will be lost. acks=all This means the leader will wait for the full set of in-sync replicas to acknowledge the record. This guarantees that the record will not be lost as long as at least one in-sync replica remains alive. This is the strongest available guarantee. This is equivalent to the acks=-1 setting. | 1 | String |
| | *camel.component.vertx-kafka.additional-properties* | Sets additional properties for either kafka consumer or kafka producer in case they can't be set directly on the camel configurations (e.g: new Kafka properties that are not reflected yet in Camel configurations), the properties have to be prefixed with additionalProperties.. E.g: additionalProperties.transactional.id=12345&additionalProperties.schema.registry.url=\http://localhost:8811/avro | | Map |
| | *camel.component.vertx-kafka.allow-auto-create-topics* | Allow automatic topic creation on the broker when subscribing to or assigning a topic. A topic being subscribed to will be automatically created only if the broker allows for it using auto.create.topics.enable broker configuration. This configuration must be set to false when using brokers older than 0.11.0 | true | Boolean |
| | *camel.component.vertx-kafka.auto-commit-interval-ms* | The frequency in milliseconds that the consumer offsets are auto-committed to Kafka if enable.auto.commit is set to true. The option is a int type. | 5000 | Integer |
| | *camel.component.vertx-kafka.auto-offset-reset* | What to do when there is no initial offset in Kafka or if the current offset does not exist any more on the server (e.g. because that data has been deleted): earliest: automatically reset the offset to the earliest offsetlatest: automatically reset the offset to the latest offsetnone: throw exception to the consumer if no previous offset is found for the consumer's groupanything else: throw exception to the consumer. | latest | String |
| | *camel.component.vertx-kafka.autowired-enabled* | Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc. | true | Boolean |
| | *camel.component.vertx-kafka.batch-size* | The producer will attempt to batch records together into fewer requests whenever multiple records are being sent to the same partition. This helps performance on both the client and the server. This configuration controls the default batch size in bytes. No attempt will be made to batch records larger than this size. Requests sent to brokers will contain multiple batches, one for each partition with data available to be sent. A small batch size will make batching less common and may reduce throughput (a batch size of zero will disable batching entirely). A very large batch size may use memory a bit more wastefully as we will always allocate a buffer of the specified batch size in anticipation of additional records. | 16384 | Integer |
| | *camel.component.vertx-kafka.bootstrap-servers* | A list of host/port pairs to use for establishing the initial connection to the Kafka cluster. The client will make use of all servers irrespective of which servers are specified here for bootstrapping—this list only impacts the initial hosts used to discover the full set of servers. This list should be in the form host1:port1,host2:port2,.... Since these servers are just used for the initial connection to discover the full cluster membership (which may change dynamically), this list need not contain the full set of servers (you may want more than one, though, in case a server is down). | | String |
| | *camel.component.vertx-kafka.bridge-error-handler* | Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored. | false | Boolean |
| | *camel.component.vertx-kafka.buffer-memory* | The total bytes of memory the producer can use to buffer records waiting to be sent to the server. If records are sent faster than they can be delivered to the server the producer will block for max.block.ms after which it will throw an exception.This setting should correspond roughly to the total memory the producer will use, but is not a hard bound since not all memory the producer uses is used for buffering. Some additional memory will be used for compression (if compression is enabled) as well as for maintaining in-flight requests. | 33554432 | Long |
| | *camel.component.vertx-kafka.check-crcs* | Automatically check the CRC32 of the records consumed. This ensures no on-the-wire or on-disk corruption to the messages occurred. This check adds some overhead, so it may be disabled in cases seeking extreme performance. | true | Boolean |
| | *camel.component.vertx-kafka.client-dns-lookup* | Controls how the client uses DNS lookups. If set to use_all_dns_ips, connect to each returned IP address in sequence until a successful connection is established. After a disconnection, the next IP is used. Once all IPs have been used once, the client resolves the IP(s) from the hostname again (both the JVM and the OS cache DNS name lookups, however). If set to resolve_canonical_bootstrap_servers_only, resolve each bootstrap address into a list of canonical names. After the bootstrap phase, this behaves the same as use_all_dns_ips. If set to default (deprecated), attempt to connect to the first IP address returned by the lookup, even if the lookup returns multiple IP addresses. | use_all_dns_ips | String |
| | *camel.component.vertx-kafka.client-id* | An id string to pass to the server when making requests. The purpose of this is to be able to track the source of requests beyond just ip/port by allowing a logical application name to be included in server-side request logging. | | String |
| | *camel.component.vertx-kafka.client-rack* | A rack identifier for this client. This can be any string value which indicates where this client is physically located. It corresponds with the broker config 'broker.rack' | | String |
| | *camel.component.vertx-kafka.compression-type* | The compression type for all data generated by the producer. The default is none (i.e. no compression). Valid values are none, gzip, snappy, lz4, or zstd. Compression is of full batches of data, so the efficacy of batching will also impact the compression ratio (more batching means better compression). | none | String |
| | *camel.component.vertx-kafka.configuration* | The component configurations. The option is a org.apache.camel.component.vertx.kafka.configuration.VertxKafkaConfiguration type. | | VertxKafkaConfiguration |
| | *camel.component.vertx-kafka.connections-max-idle-ms* | Close idle connections after the number of milliseconds specified by this config. The option is a long type. | 540000 | Long |
| | *camel.component.vertx-kafka.default-api-timeout-ms* | Specifies the timeout (in milliseconds) for client APIs. This configuration is used as the default timeout for all client operations that do not specify a timeout parameter. The option is a int type. | 60000 | Integer |
| | *camel.component.vertx-kafka.delivery-timeout-ms* | An upper bound on the time to report success or failure after a call to send() returns. This limits the total time that a record will be delayed prior to sending, the time to await acknowledgement from the broker (if expected), and the time allowed for retriable send failures. The producer may report failure to send a record earlier than this config if either an unrecoverable error is encountered, the retries have been exhausted, or the record is added to a batch which reached an earlier delivery expiration deadline. The value of this config should be greater than or equal to the sum of request.timeout.ms and linger.ms. The option is a int type. | 120000 | Integer |
| | *camel.component.vertx-kafka.enable-auto-commit* | If true the consumer's offset will be periodically committed in the background. | true | Boolean |
| | *camel.component.vertx-kafka.enable-idempotence* | When set to 'true', the producer will ensure that exactly one copy of each message is written in the stream. If 'false', producer retries due to broker failures, etc., may write duplicates of the retried message in the stream. Note that enabling idempotence requires max.in.flight.requests.per.connection to be less than or equal to 5, retries to be greater than 0 and acks must be 'all'. If these values are not explicitly set by the user, suitable values will be chosen. If incompatible values are set, a ConfigException will be thrown. | false | Boolean |
| | *camel.component.vertx-kafka.enabled* | Whether to enable auto configuration of the vertx-kafka component. This is enabled by default. | | Boolean |
| | *camel.component.vertx-kafka.exclude-internal-topics* | Whether internal topics matching a subscribed pattern should be excluded from the subscription. It is always possible to explicitly subscribe to an internal topic. | true | Boolean |
| | *camel.component.vertx-kafka.fetch-max-bytes* | The maximum amount of data the server should return for a fetch request. Records are fetched in batches by the consumer, and if the first record batch in the first non-empty partition of the fetch is larger than this value, the record batch will still be returned to ensure that the consumer can make progress. As such, this is not a absolute maximum. The maximum record batch size accepted by the broker is defined via message.max.bytes (broker config) or max.message.bytes (topic config). Note that the consumer performs multiple fetches in parallel. | 52428800 | Integer |
| | *camel.component.vertx-kafka.fetch-max-wait-ms* | The maximum amount of time the server will block before answering the fetch request if there isn't sufficient data to immediately satisfy the requirement given by fetch.min.bytes. The option is a int type. | 500 | Integer |
| | *camel.component.vertx-kafka.fetch-min-bytes* | The minimum amount of data the server should return for a fetch request. If insufficient data is available the request will wait for that much data to accumulate before answering the request. The default setting of 1 byte means that fetch requests are answered as soon as a single byte of data is available or the fetch request times out waiting for data to arrive. Setting this to something greater than 1 will cause the server to wait for larger amounts of data to accumulate which can improve server throughput a bit at the cost of some additional latency. | 1 | Integer |
| | *camel.component.vertx-kafka.group-id* | A unique string that identifies the consumer group this consumer belongs to. This property is required if the consumer uses either the group management functionality by using subscribe(topic) or the Kafka-based offset management strategy. | | String |
| | *camel.component.vertx-kafka.group-instance-id* | A unique identifier of the consumer instance provided by the end user. Only non-empty strings are permitted. If set, the consumer is treated as a static member, which means that only one instance with this ID is allowed in the consumer group at any time. This can be used in combination with a larger session timeout to avoid group rebalances caused by transient unavailability (e.g. process restarts). If not set, the consumer will join the group as a dynamic member, which is the traditional behavior. | | String |
| | *camel.component.vertx-kafka.header-filter-strategy* | To use a custom HeaderFilterStrategy to filter header to and from Camel message. The option is a org.apache.camel.spi.HeaderFilterStrategy type. | | HeaderFilterStrategy |
| | *camel.component.vertx-kafka.heartbeat-interval-ms* | The expected time between heartbeats to the consumer coordinator when using Kafka's group management facilities. Heartbeats are used to ensure that the consumer's session stays active and to facilitate rebalancing when new consumers join or leave the group. The value must be set lower than session.timeout.ms, but typically should be set no higher than 1/3 of that value. It can be adjusted even lower to control the expected time for normal rebalances. The option is a int type. | 3000 | Integer |
| | *camel.component.vertx-kafka.interceptor-classes* | A list of classes to use as interceptors. Implementing the org.apache.kafka.clients.producer.ProducerInterceptor interface allows you to intercept (and possibly mutate) the records received by the producer before they are published to the Kafka cluster. By default, there are no interceptors. | | String |
| | *camel.component.vertx-kafka.isolation-level* | Controls how to read messages written transactionally. If set to read_committed, consumer.poll() will only return transactional messages which have been committed. If set to read_uncommitted' (the default), consumer.poll() will return all messages, even transactional messages which have been aborted. Non-transactional messages will be returned unconditionally in either mode. Messages will always be returned in offset order. Hence, in read_committed mode, consumer.poll() will only return messages up to the last stable offset (LSO), which is the one less than the offset of the first open transaction. In particular any messages appearing after messages belonging to ongoing transactions will be withheld until the relevant transaction has been completed. As a result, read_committed consumers will not be able to read up to the high watermark when there are in flight transactions. Further, when in read_committed the seekToEnd method will return the LSO | read_uncommitted | String |
| | *camel.component.vertx-kafka.key-deserializer* | Deserializer class for key that implements the org.apache.kafka.common.serialization.Deserializer interface. | org.apache.kafka.common.serialization.StringDeserializer | String |
| | *camel.component.vertx-kafka.key-serializer* | Serializer class for key that implements the org.apache.kafka.common.serialization.Serializer interface. | org.apache.kafka.common.serialization.StringSerializer | String |
| | *camel.component.vertx-kafka.lazy-start-producer* | Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel's routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing. | false | Boolean |
| | *camel.component.vertx-kafka.linger-ms* | The producer groups together any records that arrive in between request transmissions into a single batched request. Normally this occurs only under load when records arrive faster than they can be sent out. However in some circumstances the client may want to reduce the number of requests even under moderate load. This setting accomplishes this by adding a small amount of artificial delay—that is, rather than immediately sending out a record the producer will wait for up to the given delay to allow other records to be sent so that the sends can be batched together. This can be thought of as analogous to Nagle's algorithm in TCP. This setting gives the upper bound on the delay for batching: once we get batch.size worth of records for a partition it will be sent immediately regardless of this setting, however if we have fewer than this many bytes accumulated for this partition we will 'linger' for the specified time waiting for more records to show up. This setting defaults to 0 (i.e. no delay). Setting linger.ms=5, for example, would have the effect of reducing the number of requests sent but would add up to 5ms of latency to records sent in the absence of load. The option is a long type. | 0 | Long |
| | *camel.component.vertx-kafka.max-block-ms* | The configuration controls how long KafkaProducer.send() and KafkaProducer.partitionsFor() will block.These methods can be blocked either because the buffer is full or metadata unavailable.Blocking in the user-supplied serializers or partitioner will not be counted against this timeout. The option is a long type. | 60000 | Long |
| | *camel.component.vertx-kafka.max-in-flight-requests-per-connection* | The maximum number of unacknowledged requests the client will send on a single connection before blocking. Note that if this setting is set to be greater than 1 and there are failed sends, there is a risk of message re-ordering due to retries (i.e., if retries are enabled). | 5 | Integer |
| | *camel.component.vertx-kafka.max-partition-fetch-bytes* | The maximum amount of data per-partition the server will return. Records are fetched in batches by the consumer. If the first record batch in the first non-empty partition of the fetch is larger than this limit, the batch will still be returned to ensure that the consumer can make progress. The maximum record batch size accepted by the broker is defined via message.max.bytes (broker config) or max.message.bytes (topic config). See fetch.max.bytes for limiting the consumer request size. | 1048576 | Integer |
| | *camel.component.vertx-kafka.max-poll-interval-ms* | The maximum delay between invocations of poll() when using consumer group management. This places an upper bound on the amount of time that the consumer can be idle before fetching more records. If poll() is not called before expiration of this timeout, then the consumer is considered failed and the group will rebalance in order to reassign the partitions to another member. For consumers using a non-null group.instance.id which reach this timeout, partitions will not be immediately reassigned. Instead, the consumer will stop sending heartbeats and partitions will be reassigned after expiration of session.timeout.ms. This mirrors the behavior of a static consumer which has shutdown. The option is a int type. | 300000 | Integer |
| | *camel.component.vertx-kafka.max-poll-records* | The maximum number of records returned in a single call to poll(). | 500 | Integer |
| | *camel.component.vertx-kafka.max-request-size* | The maximum size of a request in bytes. This setting will limit the number of record batches the producer will send in a single request to avoid sending huge requests. This is also effectively a cap on the maximum uncompressed record batch size. Note that the server has its own cap on the record batch size (after compression if compression is enabled) which may be different from this. | 1048576 | Integer |
| | *camel.component.vertx-kafka.metadata-max-age-ms* | The period of time in milliseconds after which we force a refresh of metadata even if we haven't seen any partition leadership changes to proactively discover any new brokers or partitions. The option is a long type. | 300000 | Long |
| | *camel.component.vertx-kafka.metadata-max-idle-ms* | Controls how long the producer will cache metadata for a topic that's idle. If the elapsed time since a topic was last produced to exceeds the metadata idle duration, then the topic's metadata is forgotten and the next access to it will force a metadata fetch request. The option is a long type. | 300000 | Long |
| | *camel.component.vertx-kafka.metric-reporters* | A list of classes to use as metrics reporters. Implementing the org.apache.kafka.common.metrics.MetricsReporter interface allows plugging in classes that will be notified of new metric creation. The JmxReporter is always included to register JMX statistics. | | String |
| | *camel.component.vertx-kafka.metrics-num-samples* | The number of samples maintained to compute metrics. | 2 | Integer |
| | *camel.component.vertx-kafka.metrics-recording-level* | The highest recording level for metrics. | INFO | String |
| | *camel.component.vertx-kafka.metrics-sample-window-ms* | The window of time a metrics sample is computed over. The option is a long type. | 30000 | Long |
| | *camel.component.vertx-kafka.partition-assignment-strategy* | A list of class names or class types, ordered by preference, of supported partition assignment strategies that the client will use to distribute partition ownership amongst consumer instances when group management is used.In addition to the default class specified below, you can use the org.apache.kafka.clients.consumer.RoundRobinAssignorclass for round robin assignments of partitions to consumers. Implementing the org.apache.kafka.clients.consumer.ConsumerPartitionAssignor interface allows you to plug in a custom assignmentstrategy. | org.apache.kafka.clients.consumer.RangeAssignor | String |
| | *camel.component.vertx-kafka.partition-id* | The partition to which the record will be sent (or null if no partition was specified) or read from a particular partition if set. Header VertxKafkaConstants#PARTITION_ID If configured, it will take precedence over this config | | Integer |
| | *camel.component.vertx-kafka.partitioner-class* | Partitioner class that implements the org.apache.kafka.clients.producer.Partitioner interface. | org.apache.kafka.clients.producer.internals.DefaultPartitioner | String |
| | *camel.component.vertx-kafka.receive-buffer-bytes* | The size of the TCP receive buffer (SO_RCVBUF) to use when reading data. If the value is -1, the OS default will be used. | 32768 | Integer |
| | *camel.component.vertx-kafka.reconnect-backoff-max-ms* | The maximum amount of time in milliseconds to wait when reconnecting to a broker that has repeatedly failed to connect. If provided, the backoff per host will increase exponentially for each consecutive connection failure, up to this maximum. After calculating the backoff increase, 20% random jitter is added to avoid connection storms. The option is a long type. | 1000 | Long |
| | *camel.component.vertx-kafka.reconnect-backoff-ms* | The base amount of time to wait before attempting to reconnect to a given host. This avoids repeatedly connecting to a host in a tight loop. This backoff applies to all connection attempts by the client to a broker. The option is a long type. | 50 | Long |
| | *camel.component.vertx-kafka.request-timeout-ms* | The configuration controls the maximum amount of time the client will wait for the response of a request. If the response is not received before the timeout elapses the client will resend the request if necessary or fail the request if retries are exhausted. This should be larger than replica.lag.time.max.ms (a broker configuration) to reduce the possibility of message duplication due to unnecessary producer retries. The option is a int type. | 30000 | Integer |
| | *camel.component.vertx-kafka.retries* | Setting a value greater than zero will cause the client to resend any record whose send fails with a potentially transient error. Note that this retry is no different than if the client resent the record upon receiving the error. Allowing retries without setting max.in.flight.requests.per.connection to 1 will potentially change the ordering of records because if two batches are sent to a single partition, and the first fails and is retried but the second succeeds, then the records in the second batch may appear first. Note additionally that produce requests will be failed before the number of retries has been exhausted if the timeout configured by delivery.timeout.ms expires first before successful acknowledgement. Users should generally prefer to leave this config unset and instead use delivery.timeout.ms to control retry behavior. | 2147483647 | Integer |
| | *camel.component.vertx-kafka.retry-backoff-ms* | The amount of time to wait before attempting to retry a failed request to a given topic partition. This avoids repeatedly sending requests in a tight loop under some failure scenarios. The option is a long type. | 100 | Long |
| | *camel.component.vertx-kafka.sasl-client-callback-handler-class* | The fully qualified name of a SASL client callback handler class that implements the AuthenticateCallbackHandler interface. | | String |
| | *camel.component.vertx-kafka.sasl-jaas-config* | JAAS login context parameters for SASL connections in the format used by JAAS configuration files. JAAS configuration file format is described here. The format for the value is: 'loginModuleClass controlFlag (optionName=optionValue);'. For brokers, the config must be prefixed with listener prefix and SASL mechanism name in lower-case. For example, listener.name.sasl_ssl.scram-sha-256.sasl.jaas.config=com.example.ScramLoginModule required; | | String |
| | *camel.component.vertx-kafka.sasl-kerberos-kinit-cmd* | Kerberos kinit command path. | /usr/bin/kinit | String |
| | *camel.component.vertx-kafka.sasl-kerberos-min-time-before-relogin* | Login thread sleep time between refresh attempts. | 60000 | Long |
| | *camel.component.vertx-kafka.sasl-kerberos-service-name* | The Kerberos principal name that Kafka runs as. This can be defined either in Kafka's JAAS config or in Kafka's config. | | String |
| | *camel.component.vertx-kafka.sasl-kerberos-ticket-renew-jitter* | Percentage of random jitter added to the renewal time. | | Double |
| | *camel.component.vertx-kafka.sasl-kerberos-ticket-renew-window-factor* | Login thread will sleep until the specified window factor of time from last refresh to ticket's expiry has been reached, at which time it will try to renew the ticket. | | Double |
| | *camel.component.vertx-kafka.sasl-login-callback-handler-class* | The fully qualified name of a SASL login callback handler class that implements the AuthenticateCallbackHandler interface. For brokers, login callback handler config must be prefixed with listener prefix and SASL mechanism name in lower-case. For example, listener.name.sasl_ssl.scram-sha-256.sasl.login.callback.handler.class=com.example.CustomScramLoginCallbackHandler | | String |
| | *camel.component.vertx-kafka.sasl-login-class* | The fully qualified name of a class that implements the Login interface. For brokers, login config must be prefixed with listener prefix and SASL mechanism name in lower-case. For example, listener.name.sasl_ssl.scram-sha-256.sasl.login.class=com.example.CustomScramLogin | | String |
| | *camel.component.vertx-kafka.sasl-login-refresh-buffer-seconds* | The amount of buffer time before credential expiration to maintain when refreshing a credential, in seconds. If a refresh would otherwise occur closer to expiration than the number of buffer seconds then the refresh will be moved up to maintain as much of the buffer time as possible. Legal values are between 0 and 3600 (1 hour); a default value of 300 (5 minutes) is used if no value is specified. This value and sasl.login.refresh.min.period.seconds are both ignored if their sum exceeds the remaining lifetime of a credential. Currently applies only to OAUTHBEARER. | 300 | Short |
| | *camel.component.vertx-kafka.sasl-login-refresh-min-period-seconds* | The desired minimum time for the login refresh thread to wait before refreshing a credential, in seconds. Legal values are between 0 and 900 (15 minutes); a default value of 60 (1 minute) is used if no value is specified. This value and sasl.login.refresh.buffer.seconds are both ignored if their sum exceeds the remaining lifetime of a credential. Currently applies only to OAUTHBEARER. | 60 | Short |
| | *camel.component.vertx-kafka.sasl-login-refresh-window-factor* | Login refresh thread will sleep until the specified window factor relative to the credential's lifetime has been reached, at which time it will try to refresh the credential. Legal values are between 0.5 (50%) and 1.0 (100%) inclusive; a default value of 0.8 (80%) is used if no value is specified. Currently applies only to OAUTHBEARER. | | Double |
| | *camel.component.vertx-kafka.sasl-login-refresh-window-jitter* | The maximum amount of random jitter relative to the credential's lifetime that is added to the login refresh thread's sleep time. Legal values are between 0 and 0.25 (25%) inclusive; a default value of 0.05 (5%) is used if no value is specified. Currently applies only to OAUTHBEARER. | | Double |
| | *camel.component.vertx-kafka.sasl-mechanism* | SASL mechanism used for client connections. This may be any mechanism for which a security provider is available. GSSAPI is the default mechanism. | GSSAPI | String |
| | *camel.component.vertx-kafka.security-protocol* | Protocol used to communicate with brokers. Valid values are: PLAINTEXT, SSL, SASL_PLAINTEXT, SASL_SSL. | PLAINTEXT | String |
| | *camel.component.vertx-kafka.security-providers* | A list of configurable creator classes each returning a provider implementing security algorithms. These classes should implement the org.apache.kafka.common.security.auth.SecurityProviderCreator interface. | | String |
| | *camel.component.vertx-kafka.seek-to-offset* | Set if KafkaConsumer will read from a particular offset on startup. This config will take precedence over seekTo config | | Long |
| | *camel.component.vertx-kafka.seek-to-position* | Set if KafkaConsumer will read from beginning or end on startup: beginning : read from beginning end : read from end. | | String |
| | *camel.component.vertx-kafka.send-buffer-bytes* | The size of the TCP send buffer (SO_SNDBUF) to use when sending data. If the value is -1, the OS default will be used. | 131072 | Integer |
| | *camel.component.vertx-kafka.session-timeout-ms* | The timeout used to detect client failures when using Kafka's group management facility. The client sends periodic heartbeats to indicate its liveness to the broker. If no heartbeats are received by the broker before the expiration of this session timeout, then the broker will remove this client from the group and initiate a rebalance. Note that the value must be in the allowable range as configured in the broker configuration by group.min.session.timeout.ms and group.max.session.timeout.ms. The option is a int type. | 10000 | Integer |
| | *camel.component.vertx-kafka.ssl-cipher-suites* | A list of cipher suites. This is a named combination of authentication, encryption, MAC and key exchange algorithm used to negotiate the security settings for a network connection using TLS or SSL network protocol. By default all the available cipher suites are supported. | | String |
| | *camel.component.vertx-kafka.ssl-enabled-protocols* | The list of protocols enabled for SSL connections. The default is 'TLSv1.2,TLSv1.3' when running with Java 11 or newer, 'TLSv1.2' otherwise. With the default value for Java 11, clients and servers will prefer TLSv1.3 if both support it and fallback to TLSv1.2 otherwise (assuming both support at least TLSv1.2). This default should be fine for most cases. Also see the config documentation for ssl.protocol. | TLSv1.2,TLSv1.3 | String |
| | *camel.component.vertx-kafka.ssl-endpoint-identification-algorithm* | The endpoint identification algorithm to validate server hostname using server certificate. | https | String |
| | *camel.component.vertx-kafka.ssl-engine-factory-class* | The class of type org.apache.kafka.common.security.auth.SslEngineFactory to provide SSLEngine objects. Default value is org.apache.kafka.common.security.ssl.DefaultSslEngineFactory | | String |
| | *camel.component.vertx-kafka.ssl-key-password* | The password of the private key in the key store file. This is optional for client. | | String |
| | *camel.component.vertx-kafka.ssl-keymanager-algorithm* | The algorithm used by key manager factory for SSL connections. Default value is the key manager factory algorithm configured for the Java Virtual Machine. | SunX509 | String |
| | *camel.component.vertx-kafka.ssl-keystore-location* | The location of the key store file. This is optional for client and can be used for two-way authentication for client. | | String |
| | *camel.component.vertx-kafka.ssl-keystore-password* | The store password for the key store file. This is optional for client and only needed if ssl.keystore.location is configured. | | String |
| | *camel.component.vertx-kafka.ssl-keystore-type* | The file format of the key store file. This is optional for client. | JKS | String |
| | *camel.component.vertx-kafka.ssl-protocol* | The SSL protocol used to generate the SSLContext. The default is 'TLSv1.3' when running with Java 11 or newer, 'TLSv1.2' otherwise. This value should be fine for most use cases. Allowed values in recent JVMs are 'TLSv1.2' and 'TLSv1.3'. 'TLS', 'TLSv1.1', 'SSL', 'SSLv2' and 'SSLv3' may be supported in older JVMs, but their usage is discouraged due to known security vulnerabilities. With the default value for this config and 'ssl.enabled.protocols', clients will downgrade to 'TLSv1.2' if the server does not support 'TLSv1.3'. If this config is set to 'TLSv1.2', clients will not use 'TLSv1.3' even if it is one of the values in ssl.enabled.protocols and the server only supports 'TLSv1.3'. | TLSv1.3 | String |
| | *camel.component.vertx-kafka.ssl-provider* | The name of the security provider used for SSL connections. Default value is the default security provider of the JVM. | | String |
| | *camel.component.vertx-kafka.ssl-secure-random-implementation* | The SecureRandom PRNG implementation to use for SSL cryptography operations. | | String |
| | *camel.component.vertx-kafka.ssl-trustmanager-algorithm* | The algorithm used by trust manager factory for SSL connections. Default value is the trust manager factory algorithm configured for the Java Virtual Machine. | PKIX | String |
| | *camel.component.vertx-kafka.ssl-truststore-location* | The location of the trust store file. | | String |
| | *camel.component.vertx-kafka.ssl-truststore-password* | The password for the trust store file. If a password is not set access to the truststore is still available, but integrity checking is disabled. | | String |
| | *camel.component.vertx-kafka.ssl-truststore-type* | The file format of the trust store file. | JKS | String |
| | *camel.component.vertx-kafka.transaction-timeout-ms* | The maximum amount of time in ms that the transaction coordinator will wait for a transaction status update from the producer before proactively aborting the ongoing transaction.If this value is larger than the transaction.max.timeout.ms setting in the broker, the request will fail with a InvalidTransactionTimeout error. The option is a int type. | 60000 | Integer |
| | *camel.component.vertx-kafka.transactional-id* | The TransactionalId to use for transactional delivery. This enables reliability semantics which span multiple producer sessions since it allows the client to guarantee that transactions using the same TransactionalId have been completed prior to starting any new transactions. If no TransactionalId is provided, then the producer is limited to idempotent delivery. If a TransactionalId is configured, enable.idempotence is implied. By default the TransactionId is not configured, which means transactions cannot be used. Note that, by default, transactions require a cluster of at least three brokers which is the recommended setting for production; for development you can change this, by adjusting broker setting transaction.state.log.replication.factor. | | String |
| | *camel.component.vertx-kafka.value-deserializer* | Deserializer class for value that implements the org.apache.kafka.common.serialization.Deserializer interface. | org.apache.kafka.common.serialization.StringDeserializer | String |
| | *camel.component.vertx-kafka.value-serializer* | Serializer class for value that implements the org.apache.kafka.common.serialization.Serializer interface. | org.apache.kafka.common.serialization.StringSerializer | String |
| | *camel.component.vertx-kafka.vertx* | To use an existing vertx instead of creating a new instance. The option is a io.vertx.core.Vertx type. | | Vertx |
| | *camel.component.vertx-kafka.vertx-options* | To provide a custom set of vertx options for configuring vertx. The option is a io.vertx.core.VertxOptions type. | | VertxOptions |
