> Maximize smallBuffer usage in BytesColumnVector
> -----------------------------------------------
>
> Key: HIVE-22330
> URL: https://issues.apache.org/jira/browse/HIVE-22330
> Project: Hive
> Issue Type: Improvement
> Affects Versions: 4.0.0
> Reporter: Karen Coppage
> Assignee: Karen Coppage
> Priority: Major
> Attachments: HIVE-22330.01.patch, HIVE-22330.02.patch,
> HIVE-22330.03.patch
>
>
> When BytesColumnVector is populated with values, it either creates a new
> (byte[]) buffer object to help take the values, but if the values array is
> <=1MB, then instead of creating a new buffer it reuses a single
> "smallBuffer". Every time the smallBuffer is too small for the data we want
> to store there, the size is doubled; when the size ends up larger than 1 GB
> (or Integer.MAX_VALUE / 2) then the next time we try to double the size,
> overflow occurs and an error is thrown.
> A quick fix here is to set the smallBuffer size to Integer.MAX_VALUE in this
> case.
