Subject [jira] Commented: (CASSANDRA-1546) (Yet another) approach to counting
Date Fri, 08 Oct 2010 16:42:33 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-1546?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12919317#action_12919317
] 

Kelvin Kakugawa commented on CASSANDRA-1546:
--------------------------------------------

zhu,

I wasn't clear in the last comment--the comments were UUID-specific.

Sylvain,

wrt (1), I may have better phrased it as writes are not as efficient / cheap as the default
write path, because they require a read.  And, bloom filters aren't perfect.  Granted, if
you want UUIDs, then it's prob a reasonable price to pay.
