> SinkTasks should be able to disable consumer offset commit if they manage
> offsets in the sink data store rather than using Kafka consumer offsets. For
> example, an HDFS connector might record offsets in HDFS to provide exactly
> once delivery. When the SinkTask is started or a rebalance occurs, the task
> would reload offsets from HDFS. In this case, disabling consumer offset
> commit will save some CPU cycles and network IOs.
