Subject [jira] [Commented] (CASSANDRA-11452) Cache implementation using LIRS eviction for in-process page cache
Date Thu, 14 Apr 2016 09:15:25 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11452?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15240841#comment-15240841
] 

Ben Manes commented on CASSANDRA-11452:
---------------------------------------

I did mention the attack vector during the revision, but that addition was rejected due to
concern over the peer reviewer process. Unfortunately I never investigated it further and
I'd appreciate help on that front.

How would you go about obtaining a larger hash?

> 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.
