Subject [jira] [Commented] (HBASE-16408) Handle On heap BucketCache size when HeapMemoryManager tunes memory
Date Fri, 16 Sep 2016 13:00:24 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16408?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15496270#comment-15496270
] 

stack commented on HBASE-16408:
-------------------------------

Will an on-heap bucketcache that does not make copies be faster than our lrublockcache? (Seems
like it would be?)  I'd say we can forbid it though to keep things simple (and given we don't
have much practice doing onheap bucket cache). mmap'd is considered file-based? Its not looked
on as onheap?
