Maximilian Michels commented on FLINK-15253:
--------------------------------------------
It is fine with me to make them checkpointed. I would also suggest to decouple
them from the heartbeat, to avoid heartbeat failures when they get too large.
> Accumulators are not checkpointed

> Key: FLINK-15253
> URL: https://issues.apache.org/jira/browse/FLINK-15253
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Checkpointing
> Reporter: Maximilian Michels
> Priority: Major
>
> Accumulators are not checkpointed which make them relatively useless for
> streaming applications. They are also tied to the heartbeat (FLINK-15252),
> which makes them fragile.
> We could consider deactivating accumulators in streaming mode since they seem
> to originally be a batch feature.
