Subject [jira] Updated: (HBASE-407) Client should cache region locations in an LRU structure
Date Tue, 12 Feb 2008 23:33:07 GMT

Bryan Duxbury updated HBASE-407:

    Attachment: 407-v6.patch

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