> Compaction improvements: Delayed compaction in RatioBasedCompactionPolicy
> -------------------------------------------------------------------------
>
> Key: HBASE-14496
> URL: https://issues.apache.org/jira/browse/HBASE-14496
> Project: HBase
> Issue Type: New Feature
> Reporter: Vladimir Rodionov
> Assignee: Vladimir Rodionov
> Attachments: HBASE-14496.v1.patch, HBASE-14496.v2.patch
>
>
> Delayed compaction feature for RatioBasedCompactionPolicy 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 is the more frequently it is accessed. The frequent compactions of a 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.
