Subject [jira] Commented: (CASSANDRA-1944) Support CL.QUORUM and CL.ALL for counter writes
Date Mon, 17 Jan 2011 18:53:46 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-1944?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12982795#action_12982795
] 

Jonathan Ellis commented on CASSANDRA-1944:
-------------------------------------------

I would like to see a few improvements:

- rename WriteProtocol (WritePerformer, maybe?) and doWriteProtocol to something more descriptive
- it looks like there is no per-WriteProtocol state, so we can make a singleton class each
for normal mutations and for counters, to avoid that extra anonymous object creation on each
write
- instead of not including counter stats at all, let's add an Increments set of statistics

> This ticket basically proposes to make the counter ReplicateOnWrite mechanism
