Filter out the expired store file scanner during the compaction
---------------------------------------------------------------
Key: HBASE-5274
URL: https://issues.apache.org/jira/browse/HBASE-5274
Project: HBase
Issue Type: Improvement
Reporter: Liyin Tang
Assignee: Liyin Tang
During the compaction time, HBase will generate a store scanner which will scan
a list of store files. And it would be more efficient to filer out the expired
store file since there is no need to read any key values from these store files.
This optimization has been already implemented on 89-fb and this is the
building block for HBASE-5199 as well. It is supposed to be no-ops to compact
the expired store files.
