# Camel-Kafka-connector Twitter Search Source

This is an example for Camel-Kafka-connector Twitter Search Source

## Standalone

### What is needed

- A Twitter App with Read and Write permissions

### Setting up Twitter App and get credentials

You'll need to create a twitter app and take note of access token, access token secret, consumer key and consumer secret.

### Running Kafka

```
$KAFKA_HOME/bin/zookeeper-server-start.sh $KAFKA_HOME/config/zookeeper.properties
$KAFKA_HOME/bin/kafka-server-start.sh $KAFKA_HOME/config/server.properties
$KAFKA_HOME/bin/kafka-topics.sh --create --bootstrap-server localhost:9092 --replication-factor 1 --partitions 1 --topic mytopic
```

### Setting up the needed bits and running the example

You'll need to setup the plugin.path property in your kafka

Open the `$KAFKA_HOME/config/connect-standalone.properties`

and set the `plugin.path` property to your choosen location

In this example we'll use `/home/oscerd/connectors/`

```
> cd /home/oscerd/connectors/
> wget https://repo1.maven.org/maven2/org/apache/camel/kafkaconnector/camel-twitter-search-kafka-connector/0.10.0/camel-twitter-search-kafka-connector-0.10.0-package.tar.gz
> untar.gz camel-twitter-search-kafka-connector-0.10.0-package.tar.gz
```

Now it's time to setup the connectors

Open the Twitter source configuration file

```
name=CamelTwitter-searchSourceConnector
connector.class=org.apache.camel.kafkaconnector.twittersearch.CamelTwittersearchSourceConnector
key.converter=org.apache.kafka.connect.storage.StringConverter
value.converter=org.apache.kafka.connect.storage.StringConverter

topics=mytopic

camel.source.path.keywords=Apache Camel
camel.source.endpoint.accessToken=<access_token>
camel.source.endpoint.accessTokenSecret=<access_token_secret>
camel.source.endpoint.consumerKey=<consumer_key>
camel.source.endpoint.consumerSecret=<consumer_secret>
camel.source.endpoint.count=1
```

Set the correct options in the file for the credentials part.

Now you can run the example

```
$KAFKA_HOME/bin/connect-standalone.sh $KAFKA_HOME/config/connect-standalone.properties config/CamelTwittersearchSourceConnector.properties
```

In another terminal, using kafkacat, you can consume the messages

```
> ./kafkacat -b localhost:9092 -t mytopic
