------------------------------

             Summary: [Java] Support compact fixed-width vectors
                 Key: FLINK-13054
                 URL: https://issues.apache.org/jira/browse/FLINK-13054
             Project: Flink
          Issue Type: New Feature
            Reporter: Ji Liu
            Assignee: Ji Liu


In shuffle stage of some applications, FixedWitdhVectors may have very little non-null data.
In this case, directly serialize vectors is not a good choice, generally we can compact the vector make it only holding non-null value and create a BitVector to trace the indices for non-null values so that it could be deserialized properly.
