Summary: Compaction improvements: generational compaction
Key: HBASE-14477
URL: https://issues.apache.org/jira/browse/HBASE-14477
Project: HBase
Issue Type: New Feature
Reporter: Vladimir Rodionov
Assignee: Vladimir Rodionov
Fix For: 2.0.0
For immutable and mostly immutable data the current SizeTiered-based compaction
policy is not efficient.
# There is no need to compact all files into one, because, data is (mostly)
immutable and we do not need to collect garbage. (performance reason will be
discussed later)
# Size-tiered compaction is not suitable for applications where most recent
data is most important and prevents efficient caching of this data.
