Version 3.0 of the Kafka Sink Connector introduces a new configuration property, used in error scenarios - graphdb.sink.poll.backoff.timeout.ms.
This property is used to slow down record ingestion in case of downstream congestion - those that are intermittent and in which case data flush has failed and
will be retried at a later point in time. The default value is set to 10000 ms, and can be kept as is.
Because the connector is stateless, no data is kept on disk where the connector is running. Therefore, upgrading the version of the connector would simply require a restart of the services and re-configuration of the connector instances.
The existing producer runtime, which eases the creation of Kafka records and their subsequent ingestion, has been removed
