Subject [jira] [Created] (HBASE-18708) Configure on-heap bucketCache size using percentage of heap size
Date Mon, 28 Aug 2017 17:02:00 GMT

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

             Summary: Configure on-heap bucketCache size using percentage of heap size
                 Key: HBASE-18708
                 URL: https://issues.apache.org/jira/browse/HBASE-18708
             Project: HBase
          Issue Type: Improvement
          Components: regionserver
            Reporter: Biju Nair
            Priority: Trivial


Currently heap allocations for RS memory structures like {{memstore}} and {{lruCache}} are
configured as percentage of total RS heap size. Since on-heap bucketCache uses RS heap, configuring
it as a percentage of heap size will improve usability. Currently this can be configured either
as a percentage of heap or a memory size in MiB and we can remove the latter option which
is applicable to external or off-heap bucketCache.
