Subject [jira] Commented: (HBASE-407) Client should cache region locations in an LRU structure
Date Mon, 11 Feb 2008 18:24:07 GMT

    [ https://issues.apache.org/jira/browse/HBASE-407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12567738#action_12567738

stack commented on HBASE-407:

I think we should spend the time verifying SoftReferences are working the way you expect because
then we can use them elsewhere with some confidence.  I'll take a look B.

Hey, if you're going to have a mess -- have it in one place rather than distributed (smile).

Yeah, finals are good.  They serve as hints to compiler and allows it take optimal paths that
it would otherwise be wary making (I have no numbers -- just citing "the literature").

> Instead of keeping the region locations cached client side in a TreeMap, we should use
an LRU mechanism to help manage memory more dynamically.
