------------------------------------------
Summary: 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
Accumulators are not checkpointed which make them relatively useless for
streaming applications. They are also tight 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.
