> URL: https://issues.apache.org/jira/browse/HBASE-1011
> Project: Hadoop HBase
> Issue Type: New Feature
> Reporter: Jonathan Gray
>
> In thinking about ways to improve random-read access, a very typical access
> pattern for web sites is to primarily be retrieving from new records but
> having a much larger total dataset in a given table.
> If you could specify a Memcache flush TTL, you could keep "past 24 hours" in
> memory and this would give you a sliding window updated on memcache flushes.
> Must also adapt to regionserver memory pressure.
