> Wrong state array size in NestedMapsStateTable

> Key: FLINK-6899
> URL: https://issues.apache.org/jira/browse/FLINK-6899
> Project: Flink
> Issue Type: Bug
> Components: State Backends, Checkpointing
> Affects Versions: 1.3.0, 1.4.0
> Reporter: Till Rohrmann
> Assignee: Till Rohrmann
> Priority: Minor
> Fix For: 1.4.0
>
>
> The {{NestedMapsStateTable}} initializes the internal state array with a
> wrong size which leads to a waste of memory. We should initialize the array
> with the number of key groups of the assigned range instead of the max
> parallelism.
