Subject [jira] Commented: (HBASE-674) memcache size unreliable
Date Mon, 09 Jun 2008 21:36:45 GMT

    [ https://issues.apache.org/jira/browse/HBASE-674?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12603699#action_12603699

Jim Kellerman commented on HBASE-674:

Good catch! 

We should probably update the memcache size with each update, and if we are overwriting a
previous update we need to take that into account.

> Multiple updates against same row/column/ts will be seen as increments to cache size
on insert but when we then play the memcache at flush time, we'll only see the most recent
entry and decrement the memcache size by whatever its size; memcache will be off.
