Summary: 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 - Vectors
Reporter: Siddharth Teotia
Assignee: Siddharth Teotia
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.
