------------------------------------
Dup HBASE-2265?
> Track and persist max/min timestamp per StoreFile in HFile meta block
> ---------------------------------------------------------------------
>
> Key: HBASE-2776
> URL: https://issues.apache.org/jira/browse/HBASE-2776
> Project: HBase
> Issue Type: New Feature
> Components: io, regionserver
> Reporter: Jonathan Gray
>
> This is an idea to help optimize cases where a user asks for a specific
> TimeStamp or TimeRange in their query.
> If specifying a TimeRange, we are unable to use any kind of bloom to
> determine whether we need to open every file or not. If we knew the max/min
> timestamps in each file, we could use that information to prevent opening
> files we know do not contain any versions from the query's TimeRange.
