-------------------------------------------
Summary: Optimize writes of zero length values in compressed WALs
Key: HBASE-27640
URL: https://issues.apache.org/jira/browse/HBASE-27640
Project: HBase
Issue Type: Sub-task
Reporter: Andrew Kyle Purtell
Fix For: 2.6.0, 3.0.0-alpha-4
If we unconditionally use the compressor, to "write" 0 bytes, then the
compression codec will emit overheads... hadoop compressionstream header,
compression bitstream header. All of that should be skipped so truly no
compressed value data is written when the value is empty.
