> Honor ByteBuffer position and limit when writing compressed B-Tree pages
> ------------------------------------------------------------------------
>
> Key: ASTERIXDB-3360
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-3360
> Project: Apache AsterixDB
> Issue Type: Improvement
> Components: STO - Storage
> Affects Versions: 0.9.9
> Reporter: Wail Y. Alkowaileet
> Assignee: Wail Y. Alkowaileet
> Priority: Major
> Labels: triaged
> Fix For: 0.9.9
>
>
> Compressed page writer always clear the to-be-written ByteBuffer position and
> limit to be the entire buffer. This could be fine for writing pages in row
> format. However, in columnar format, this might incur compressing and writing
> unrelated data (as the ByteBuffer may contain data from a previous write).
> Instead of clearing the ByteBuffer position and limit at the compressed page
> writer, it should be done during the call to BufferCache#confiscatePage(),
> which is the case currently. The compressed page writer, however, should not
> re-clear whatever limit is provided.
