Hi Sjoerd, We've added kafka.group.id config to Spark 3.0...
kafka.group.id string none streaming and batch The Kafka group id to use in Kafka consumer while reading from Kafka. Use this with caution. By default, each query generates a unique group id for reading data. This ensures that each Kafka source has its own consumer group that does not face interference from any other consumer, and therefore can read all of the partitions of its subscribed topics. In some scenarios (for example, Kafka group-based authorization), you may want to use a specific authorized group id to read data. You can optionally set the group id. However, do this with extreme caution as it can cause unexpected behavior. Concurrently running queries (both, batch and streaming) or sources with the same group id are likely interfere with each other causing each query to read only part of the data. This may also occur when queries are started/restarted in quick succession. To minimize such issues, set the Kafka consumer session timeout (by setting option "kafka.session.timeout.ms") to be very small. When this is set, option "groupIdPrefix" will be ignored.
