Subject [jira] Commented: (HBASE-1304) New client server implementation of how gets and puts are handled.
Date Sun, 17 May 2009 08:47:45 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1304?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12710183#action_12710183

ryan rawson commented on HBASE-1304:
------------------------------------

I'm just thinking about what the usage scenario for deletes are - ultimately if you want a
different value instead of the original, you are better off to just insert over, rather than
to delete then put again.  

Deleting immediately from the memcache is fine with me.

So the question is, do we want the complexity of deletes in the scan/get, or do we want to
take the higher hit on compactions - potentially.  I don't think compaction & deletion
at the same time is overly complex, and if it makes the scan/get simpler, then perhaps it
would be best.

So far I don't think the scan delete tracker works - can you confirm/deny?
