Subject [jira] [Commented] (CASSANDRA-2443) Stream key/row caches during bootstrap
Date Fri, 20 Sep 2013 21:16:53 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2443?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13773437#comment-13773437
] 

Yuki Morishita commented on CASSANDRA-2443:
-------------------------------------------

We can't just stream key cache because file names and position change, though it may be possible
to build Bloom Filter of cached keys and stream it before files, and the bootstrapping node
can build it's own key cache as it receives SSTables.

> When adding new nodes to an existing cluster, if we streamed key and row caches over
right before node came into cluster, we could minimize the impact of a cold node, and reduce
the time for the node to get 'warmed' up.
