Flink Jira Bot updated FLINK-27311:
-----------------------------------
Labels: MapState State rocksdb stale-major (was: MapState State rocksdb)
I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help
the community manage its development. I see this issues has been marked as
Major but is unassigned and neither itself nor its Sub-Tasks have been updated
for 60 days. I have gone ahead and added a "stale-major" to the issue". If this
ticket is a Major, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.
> Rocksdb mapstate behaves unexpectedly
> --------------------------------------
>
> Key: FLINK-27311
> URL: https://issues.apache.org/jira/browse/FLINK-27311
> Project: Flink
> Issue Type: Bug
> Components: Runtime / State Backends, Stateful Functions
> Affects Versions: 1.14.4
> Environment: Kubernetes
> Reporter: Jonathan diamant
> Priority: Major
> Labels: MapState, State, rocksdb, stale-major
>
> We use rocksDb backend for our state and we experience an unexpected
> behavior. The state we use is MapState<String, List<Object>> and when a
> restart occurs and the state is being recovered from the last checkpoints, it
> seems that not all the list corresponding to a certain key has been loaded
> and only after all the state has been recovered it behaves as expected.
> Our guess is that while recovering the state, rocksdb recovers the state in
> chunks and loads entries of the map not as a whole even though we expect that
> for every key, the value (a list) will be loaded as one object at once.
