------------------------------------------
Summary: 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.
