> Variable length vectors use unnecessary emptyByteArray to fill empties
> ----------------------------------------------------------------------
>
> Key: DRILL-6596
> URL: https://issues.apache.org/jira/browse/DRILL-6596
> Project: Apache Drill
> Issue Type: Bug
> Reporter: Parth Chandra
> Priority: Major
>
> When writing to an index beyond the last index written to, Variable Length
> vectors set the 'empties' by writing a zero length byte array to the indexes
> that were skipped.
> This is, as it turns out, sometimes an expensive operation, and is completely
> unnecessary as all that needs to be done is to set the offset vector
> correctly.
