Subject [jira] Commented: (CASSANDRA-1501) remove Clock from Thrift API
Date Tue, 14 Sep 2010 17:53:33 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-1501?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12909355#action_12909355
] 

Jonathan Ellis commented on CASSANDRA-1501:
-------------------------------------------

the Clock interface adds a ton of wrapping/unwrapping to the "normal" mutation path (which
is probably why 0.7 insert performance is virtually unchanged from 0.6 despite dropping String
keys).  I don't think that's the right place for this; treating increments as a special value
rather than a special clock makes more sense.

> Clock was introduced back when we insufficiently understood the limitations of CASSANDRA-580.
It turns out to not be necessary. This ticket removes it from the Thrift API to get ready
for 0.7.0; removing it from the rest of the internals can follow.
