Aljoscha Krettek updated FLINK-15253:
-------------------------------------
Description:
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.
