Subject [jira] [Commented] (HBASE-13170) Allow block cache to be external
Date Sat, 07 Mar 2015 17:46:38 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13170?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14351715#comment-14351715

stack commented on HBASE-13170:

Sounds cool.  What about us peons who don't happen to have an idle memcached cluster hanging
about or you think starting up a bunch of memcached's doable by proles too? (HBase starts
zk, could start companion memcached too...)

> Allow an external service to provide the block cache. This has the nice property of allowing
failover/upgrades to happen without causing a fully cold cache.
> Additionally this allows read replicas to share some of the same memory.
