-----------------------------------------
Summary: Compaction improvements: delayed compaction
Key: HBASE-14496
URL: https://issues.apache.org/jira/browse/HBASE-14496
Project: HBase
Issue Type: New Feature
Reporter: Vladimir Rodionov
Assignee: Vladimir Rodionov
Delayed compaction feature allows to specify maximum compaction delay for newly
created store files. Files will be eligible for compaction only if their age
exceeds this delay. This will allow to preserve new data in a block cache. For
most applications, the newer the data the more frequently is accessed. The
frequent compactions of new store files result in high block cache churn rate
and affects read performance and read latencies badly.
The configuration will be global, per table, per column family.
