Ji Liu created FLINK-13054: ------------------------------ 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
