Ji Liu updated FLINK-13054:
---------------------------
Description:
was:
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.
> [Java] Support compact fixed-width vectors
