| <div class="block">Configuration for a <a href="../../../../org/apache/kafka/streams/KafkaStreams.html" title="class in org.apache.kafka.streams"><code>KafkaStreams</code></a> instance. |
| Can also be use to configure the Kafka Streams internal <a href="../../../../org/apache/kafka/clients/consumer/KafkaConsumer.html" title="class in org.apache.kafka.clients.consumer"><code>KafkaConsumer</code></a> and <a href="../../../../org/apache/kafka/clients/producer/KafkaProducer.html" title="class in org.apache.kafka.clients.producer"><code>KafkaProducer</code></a>. |
| To avoid consumer/producer property conflicts, you should prefix those properties using |
| <a href="../../../../org/apache/kafka/streams/StreamsConfig.html#consumerPrefix(java.lang.String)"><code>consumerPrefix(String)</code></a> and <a href="../../../../org/apache/kafka/streams/StreamsConfig.html#producerPrefix(java.lang.String)"><code>producerPrefix(String)</code></a>, respectively. |
| <p> |
| Example: |
| <pre><code>// potentially wrong: sets "metadata.max.age.ms" to 1 minute for producer AND consumer |
| Properties streamsProperties = new Properties(); |
| streamsProperties.put(ConsumerConfig.METADATA_MAX_AGE_CONFIG, 60000); |
| // or |
| streamsProperties.put(ProducerConfig.METADATA_MAX_AGE_CONFIG, 60000); |
| |
| // suggested: |
| Properties streamsProperties = new Properties(); |
| // sets "metadata.max.age.ms" to 1 minute for consumer only |
| streamsProperties.put(StreamsConfig.consumerPrefix(ConsumerConfig.METADATA_MAX_AGE_CONFIG), 60000); |
| // sets "metadata.max.age.ms" to 1 minute for producer only |
| streamsProperties.put(StreamsConfig.producerPrefix(ProducerConfig.METADATA_MAX_AGE_CONFIG), 60000); |
| |
| StreamsConfig streamsConfig = new StreamsConfig(streamsProperties); |
| </code></pre> |
| Kafka Streams required to set at least properties <a href="../../../../org/apache/kafka/streams/StreamsConfig.html#APPLICATION_ID_CONFIG"><code>"application.id"</code></a> and |
| <a href="../../../../org/apache/kafka/streams/StreamsConfig.html#BOOTSTRAP_SERVERS_CONFIG"><code>"bootstrap.servers"</code></a>. |
