Incremental counters
Hi.
apologies in advance, as I haven't been keeping current on what is going on in cassandra-land for a while.
I noticed that incremental counters have been added to 0.8/Trunk in CASSANDRA-1072.
I was wondering if this (and supporting patches?) could be easily applied to 0.74, or if the current trunk is stable enough to use.
I think twitter is using this in their Rainman product.. ideally they will release that soon as well ;-)
Thanks in advance

We no longer backport to 0.7. We're on 0.8/trunk at the moment.

https://github.com/kakugawa/cassandra/tree/twttr-cassandra-0.7-counts
Contains a version of 0.7 with a version of the counters patch
applied. Twitter could speak to whether they are likely to continue to
update this public branch..

PS - note that unless that version contains
https://issues.apache.org/jira/browse/CASSANDRA-1938, you will have to
dump and reload counts when you get to a version which does contain
it.

Beta should start shortly after the freeze on April 11th.

We're very interested in the distributed counter feature as well. Jonathan,
when you say early May, is that for a beta release or are you planning on
being done with the beta / RC cycle by then? We got burned on the 0.7 beta
cycle and implemented way too early, I don't want to make the same mistake
again.
Thanks

The bad news is that counters are considered too invasive to backport
to 0.7. Original patch was 250KB and there have been several
nontrivial changes since.
The good news is that 0.8 is planned for early May.
