Jonathan Gray updated HBASE-2500: --------------------------------- Fix Version/s: (was: 0.90.0) 0.92.0 This really should be done, but punting to 0.92 because won't be done in time for 0.90. > Block indexes and meta blocks should be put into the LRU > -------------------------------------------------------- > > Key: HBASE-2500 > URL: https://issues.apache.org/jira/browse/HBASE-2500 > Project: HBase > Issue Type: Improvement > Components: regionserver > Reporter: Jonathan Gray > Assignee: Nicolas Spiegelberg > Priority: Minor > Fix For: 0.92.0 > > > Currently we are not tracking the heap usage of block indexes. We're just > relying on the fact that we leave a large percentage of total heap as part of > "everything else" not in memstores or the block cache. The "everything else" > portion should be left for ephemeral/transient memory usage, not long-lived > objects like block indexes. Introduction of blooms will extend this issue to > meta blocks in general. > All of this should be moved into an LRU. Either the existing block cache LRU > or a new LRU. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
