• exactly_once_source_support | boolean

  Whether to enable exactly-once support for source connectors in the cluster by using transactions to write source records and their source offsets, and by proactively fencing out old task generations before bringing up new ones.

• key_converter | string

  Default: org.apache.kafka.connect.json.JsonConverter

  Converter class used to convert between Kafka Connect format and the serialized form that is written to Kafka. This controls the format of the keys in messages written to or read from Kafka, and since this is independent of connectors, it allows any connector to work with any serialization format. Examples of common formats include JSON and Avro.

  Note: For custom converters, the library files should be provided to the charm beforehand using juju attach-resource command. Please refer to the docs for more details.

• log_level | string

  Default: INFO

  Level of logging for the Apache Kafka Connect service operated by the charm.

  Allowed values are: "ERROR", "WARNING", "INFO", and "DEBUG".

• profile | string

  Default: production

  Profile representing the scope of deployment, and used to enable high-level customisation of configs, resource checks/allocation, logging levels, etc.

  Allowed values are: "production" and "testing".

• rest_port | int

  Default: 8083

  Port used for Apache Kafka Connect REST API endpoint.

• system-users | string

  User-provided secret ID which defines custom username/passwords on the Kafka Connect REST Interface. The secret ID format is like "secret:cvh7kruupa1s46bqvuig" and should not be confused with secret name or label.

  The secret could be defined using juju add-secret <secret-name> u1=p1 u2=p2 ... command, where keys (u1..n) are usernames and values (p1..n) are passwords. The juju add-secret command will output the secret ID, which can then be granted to the charm and configured using juju config command. The following example shows the complete flow:

  $ juju add-secret my-auth admin=adminpass user1=user1pass user2=user2pass

  some ID will be printed: e.g. "secret:cvh7kruupa1s46bqvuig". take note of that.

  $ juju grant-secret my-auth kafka-connect $ juju config kafka-connect auth=secret:cvh7kruupa1s46bqvuig

• value_converter | string

  Default: org.apache.kafka.connect.json.JsonConverter

  Converter class used to convert between Kafka Connect format and the serialized form that is written to Kafka. This controls the format of the values in messages written to or read from Kafka, and since this is independent of connectors, it allows any connector to work with any serialization format. Examples of common formats include JSON and Avro.
