Ji Liu closed FLINK-13054. -------------------------- Resolution: Invalid > [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 > Priority: Minor > > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
