Subject [jira] [Commented] (HBASE-16417) In-Memory MemStore Policy for Flattening and Compactions
Date Sat, 10 Sep 2016 19:40:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16417?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15480321#comment-15480321

Anastasia Braginsky commented on HBASE-16417:

Hi again!

As I started to explain in my previous comment, we believe this JIRA should be split into
two. I have opened HBASE-16608 for this case. In HBASE-16608 we want to present the merge
of the immutable segments of the pipeline into one new segment, while this is done without
data-copy-compaction and without SQM.

In this JIRA we plan to continue after HBASE-16608 and finalize the tuning of the in-memory
flush policy for the best performance. All the performance issues are still meant to be resolved
here. HBASE-16608 is for one more "algorithmic issue", not so sophisticated of course, but
should resolve us the issues of two many segments (and later files) in the compaction pipeline.
I would like to hear your opinion about all that! For more details look on HBASE-16608.

Waiting for your fruitful thoughts!
