Subject [jira] [Commented] (CASSANDRA-11452) Cache implementation using LIRS eviction for in-process page cache
Date Wed, 27 Apr 2016 06:42:12 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11452?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15259639#comment-15259639

Branimir Lambov commented on CASSANDRA-11452:
---------------------------------------------

Roy has left out the "access on equality" option. Reading this I understand it to make even
more sense -- because of the counter saturation in essence it would act very similar to Option
7 without the performance hit.

> Following up from CASSANDRA-5863, to make best use of caching and to avoid having to
explicitly marking compaction accesses as non-cacheable, we need a cache implementation that
uses an eviction algorithm that can better handle non-recurring accesses.
