> [Java] Fix splitAndTransfer for variable width vector
> -----------------------------------------------------
>
> Key: ARROW-2294
> URL: https://issues.apache.org/jira/browse/ARROW-2294
> Project: Apache Arrow
> Issue Type: Bug
> Components: Java
> Reporter: Siddharth Teotia
> Priority: Major
>
> When we splitAndTransfer a vector, the value count to set for the target
> vector should be equal to split length and not the value count of source
> vector.
> We have seen cases in operator slike FLATTEN and under low memory conditions,
> we end up allocating a lot more memory for the target vector because of using
> a large value in setValueCount after split and transfer is done.
