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.

I think of them as the println debugging of metrics in Flink. I use them when I need to troubleshoot a job and I'm not sure where I'm looking but agreed that they are not appropriate for production streaming applications. > 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.
