-----------------------------------------

Just learned about https://issues.apache.org/jira/browse/KAFKA-12980 – we should verify it it would actually fix this issue, similar to https://issues.apache.org/jira/browse/KAFKA-14713

> Using "exactly_once_beta" the highWatermark "skips" an offset after a transaction but in this case the global .checkpoint file contains different value (smaller by 1) than the highWatermark.
> During restoration because of the difference between the checkpoint and highWatermark a poll will be attempted but sometimes there is no new record on the partition and the GlobalStreamThread has to wait for the requestTimeout to continue.
> If there is any new record on the partition the problem does not occure.
