Phabricator commented on HBASE-5033: ------------------------------------ Liyin has commented on the revision "[jira][HBASE-5033][[89-fb]]Opening/Closing store in parallel to reduce region open/close time". INLINE COMMENTS src/main/java/org/apache/hadoop/hbase/regionserver/HRegion.java:807 The region server will retry to close the store if the previous close operation failed. So a local thread pool makes more sense here. src/main/java/org/apache/hadoop/hbase/HConstants.java:193 I will update to "hbase.hstore.open.close.threads.max" REVISION DETAIL https://reviews.facebook.net/D933 > Opening/Closing store in parallel to reduce region open/close time > ------------------------------------------------------------------ > > Key: HBASE-5033 > URL: https://issues.apache.org/jira/browse/HBASE-5033 > Project: HBase > Issue Type: Improvement > Reporter: Liyin Tang > Assignee: Liyin Tang > Attachments: D933.1.patch, D933.2.patch, D933.3.patch, D933.4.patch > > > Region servers are opening/closing each store and each store file for every > store in sequential fashion, which may cause inefficiency to open/close > regions. > So this diff is to open/close each store in parallel in order to reduce > region open/close time. Also it would help to reduce the cluster restart time. > 1) Opening each store in parallel > 2) Loading each store file for every store in parallel > 3) Closing each store in parallel > 4) Closing each store file for every store in parallel. -- This message is automatically generated by JIRA.
