Andrew Kyle Purtell updated HBASE-25756:
----------------------------------------
Hadoop Flags: Reviewed
Release Note: It is now possible to specify alternate compression
algorithms for major or minor compactions, via new ColumnFamilyBuilder or
HColumnDescriptor methods {get,set}{Major,Minor}CompressionType(), or shell
schema attributes COMPRESSION_COMPACT_MAJOR or COMPRESSION_COMPACT_MINOR. This
can be used to select a fast algorithm for frequent minor compactions and a
slower algorithm offering better compression ratios for infrequent major
compactions.
Resolution: Fixed
Status: Resolved (was: Patch Available)
> Support alternate compression for major and minor compactions

> Key: HBASE-25756

> Project: HBase
> Issue Type: New Feature
> Components: Compaction
> Reporter: Andrew Kyle Purtell

> Resurrecting HBASE-2988.
> Currently we can specify a compression algorithm for a column family, or,
> optionally an alternative compression algorithm to use when compacting (as
> opposed to flushing). Extend this to optionally specify alternative
> compression algorithms for minor or major compactions. The interest here is
> specifically a separate alternative algorithm for major compactions, which
> might be an expensive but aggressively compressing algorithm like bzip2 or
> lzma (with custom patches).
