Subject [jira] [Commented] (ACCUMULO-4466) Investigate TinyLFU as default block cache implementation
Date Wed, 05 Oct 2016 18:50:20 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-4466?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15549627#comment-15549627

Ben Manes commented on ACCUMULO-4466:
-------------------------------------

The performance analysis was decided to be a pre-req for integrating [HBASE-15560|https://issues.apache.org/jira/browse/HBASE-15560].
It might be acceptable to piggyback on that evaluation.

> ACCUMULO-4177 brought in TinyLfuBlockCache which shows some potential over our LruMap
from HBase.
> We should run some benchmarks that we can stand behind and determine if we should be
switching the default cache implementation.
