Junhong Xu commented on HBASE-24436: ------------------------------------ bq. And how much slower open a store which has 20 storefiles VS open a store which has 1 storefile? Give some metric or data to show the benefit of this improvement? I am preparing for the data.Although we have reached no agreement on the solution itself so far, the data is very important > The store file open and close thread pool should be shared at the region level > ------------------------------------------------------------------------------ > > Key: HBASE-24436 > URL: https://issues.apache.org/jira/browse/HBASE-24436 > Project: HBase > Issue Type: Improvement > Reporter: Junhong Xu > Assignee: Junhong Xu > Priority: Minor > > For now, we provide threads per column family evenly in general, but there > are some cases that some column families have much more store files than > others( maybe that's the life, right? ).
