Subject [jira] [Created] (HBASE-18165) Predicate based deletion during major compactions
Date Mon, 05 Jun 2017 20:55:04 GMT

-------------------------------------

             Summary: Predicate based deletion during major compactions
                 Key: HBASE-18165
                 URL: https://issues.apache.org/jira/browse/HBASE-18165
             Project: HBase
          Issue Type: Brainstorming
            Reporter: Lars Hofhansl


In many cases it is expensive to place a delete per version, column, or family.
HBase should have way to specify a predicate and remove all Cells matching the predicate during
the next compactions (major and minor).

Nothing more concrete. The tricky part would be to know when it is safe to remove the predicate,
i.e. when we can be sure that all Cells matching the predicate actually have been removed.

Could potentially use HBASE-12859 for that.
