Wei-Chiu Chuang updated HDDS-12491:
-----------------------------------
Parent: HDDS-13747 (was: HDDS-12940)
> Snapshot diff should use direct byte buffers on SSTFileReader and
> RawSstFileReader while fetching keys
> ------------------------------------------------------------------------------------------------------
>
> Key: HDDS-12491
> URL: https://issues.apache.org/jira/browse/HDDS-12491
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Swaminathan Balachandran
> Assignee: Swaminathan Balachandran
> Priority: Major
>
> Currently SnapshotDiff creates a new byte array for each and every key read
> from sstFileReaderIterator & RawSstFileIterator which would cause a lot of
> unnecessary GC. We should use Direct ByteBuffer instead this wasn't done in
> the V1 since we wanted to first stabilise the native lib and then look for
> performance optimizations in this flow.
