[jira] [Created] (FLINK-6899) Wrong state array size in NestedMapsStateTable

Till Rohrmann created FLINK-6899:
------------------------------------

             Summary: 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.
