> Key: FLINK-5530
> URL: https://issues.apache.org/jira/browse/FLINK-5530
> Project: Flink
> Issue Type: Bug
> Components: Queryable State
> Affects Versions: 1.2.0
> Reporter: Nico Kruber
> Assignee: Nico Kruber
> Priority: Blocker
> Fix For: 1.2.0, 1.3.0
>
>
> AbstractRocksDBState#getSerializedValue() uses the same key serialisation
> stream as the ordinary state access methods but is called in parallel during
> state queries thus violating the assumption of only one thread accessing it.
> This may lead to either wrong results in queries or corrupt data while
> queries are executed.
