I am trying to use kafka connect in a docker container with a custom connector (PROGRESS_DATADIRECT_JDBC_OE_ALL.jar) to connect to an openedge database.

JDBC Drivers are not Connect plugins, nor are they connectors themselves.

You'd need to set the JVM CLASSPATH environment variable for detecting JDBC Drivers, as with any Java process.

The instructions on the linked site suggest you should copy the JDBC Drivers into the directory for the existing Confluent JDBC connector. While you could use a Docker COPY command, the better way would be to use confluent-hub install

If you're writing straight JSON from your Python app then you'll need to use the org.apache.kafka.connect.json.JsonConverter converter, but your messages will need a schema and payload attribute.

io.confluent.connect.json.JsonSchemaConverter relies on the Schema Registry wire format which includes a "magic byte" (hence the error).

You can learn more in this deep-dive article about serialisation and Kafka Connect, and see how Python can produce JSON data with a schema using SerializingProducer

Docker volumes are ephemeral, so this is expected behavior.

You need to mount host volumes for at least the Kafka and Zookeeper containers

You need to set correctly rest.advertised.host.name (or CONNECT_REST_ADVERTISED_HOST_NAME, if you’re using Docker). This is how a Connect worker communicates with other workers in the cluster.

For more details see Common mistakes made when configuring multiple Kafka Connect workers by Robin Moffatt.

In your case try to remove CONNECT_REST_ADVERTISED_HOST_NAME=localhost from compose file.

Read current incrementing value of Confluent Kafka Source Connector with Rest?

Asked 2021-Jun-29 at 15:13

I have a Kafka Source Connector using the io.confluent.connect.jdbc.JdbcSourceConnector class. It is run in incrementing mode.

I can access this connector via the Rest interface. To examine a problem I want to know the current incrementing value of this connector.

Is there a way to read the current incrementing value with Rest?

...

ANSWER

Answered 2021-Jun-29 at 15:10

That information is not available via REST because there are no special endpoints that specific connectors provide that are not uniform across all others (in other words, you only get the /config that you posted and its /status)

If you would like to dig into the connector metadata, you'll have to consume the internal offsets topic. e.g. see this post on Resetting the Source Offset

to install SMT it just the same as installing other connector,

Copy your custom SMT JAR file (and any non-Kafka JAR files required by the transformation) into a directory that is under one of the directories listed in the plugin.path property in the Connect worker configuration –

In your case copy to /usr/share/confluent-hub-components

Except that I'm not running kafka connect worker on GCP but locally.

ANSWER

Answered 2021-Jun-11 at 14:27

I managed to get it to work, this is a correct configuration...

The message "Unable to connect to the server" was because I had wrongly deployed mongo instance so it's not related to kafka-connect or confluent cloud.

I'm going to leave this question as an example if somebody struggles with this in the future. It took me a while to figure out how to configure docker-compose for kafka-connect that connects to confluent cloud.
