             Summary: Major compaction completion tracker
                 Key: HBASE-12859
                 URL: https://issues.apache.org/jira/browse/HBASE-12859
             Project: HBase
          Issue Type: Brainstorming
            Reporter: Lars Hofhansl

In various scenarios it is helpful to know a guaranteed timestamp up to which all data in
a table was major compacted.
We can do that keeping a major compaction timestamp in META.
A client then can iterate all region of a table and find a definite timestamp, which is the
oldest compaction timestamp of any of the regions.
