Subject [jira] [Commented] (HBASE-15389) Write out multiple files when compaction
Date Mon, 07 Mar 2016 23:29:40 GMT

Lars Hofhansl commented on HBASE-15389:
---------------------------------------

[~Apache9] thanks for looking into this. This is awesome.

Looks good, generally - still have to look through the details.

Questions:
# where does that leave DateTieredCompactionPolicy? Would we remove that?
# I notice the Windowing logic in DateTieredMultiFileWriter is different from the one in DateTieredCompactionPolicy.
Can you explain the difference?
