-----------------------------------------------
[^trace.zip]
Oddly enough I see this kind of often in a dummy cluster, and I actually
managed to get trace logs. It's really strange because it happened even when
the Kafka topics were not receiving anything, maybe Kafka offsets expired? I
also wonder if Kafka disconnects are cause or effect. In case it's relevant,
the Kafka clusters have 3 nodes and the topics have retention of 24h.

> In the case of unaligned checkpoints, it might happen that the checkpoint

> that needs to be correct at a later point when the records arrive.
