-----------------------------------
Resolution: Not A Problem
> Change Compression Based on Type of Compaction
> ----------------------------------------------
>
> Key: HBASE-5891
> URL: https://issues.apache.org/jira/browse/HBASE-5891
> Project: HBase
> Issue Type: New Feature
> Reporter: Nicolas Spiegelberg
> Priority: Minor
>
> We currently use LZO on our production systems because the on-demand
> decompression speed of GZ is too slow. That said, many of our
> major-compacted StoreFiles are infrequently read because of lazy seek
> optimizations, but they occupy the majority of our disk space. One idea is
> to change the type of compression depending upon compaction characteristics
> (input size or major compaction flag). This would allow us to have our
> largest and least-read files be GZ compressed and save space.
