Re: Hive + Cassandra
There are actually several storage handlers floating out in the wild for Mongo, Cassandra, HyperTable, etc. Your best bet is referencing the Cassandra ticket and building/using the brisk/dse code. Eventually the code will make it's way into Cassandra. It is a shame the code has been in production in numerous sites for over a year now, and is the most voted for hive issue, but has not landed into a release, thus confusing everyone. Look here for the latest code. https://issues.apache.org/jira/browse/CASSANDRA-4131 On Tue, May 22, 2012 at 4:19 AM, Szymon Dąbrowski szymon.dabrow...@gmail.com wrote: I've been trying to see if that's possible to combine Hive with Cassandra. I've noticed some issues about integration but it seems to me there's some mix-up about who is to patch things up. There are two issues: in Hive project [1] and in Cassandra [2]. The first one is opened, but it ends with comment which says the patch has been send to the second issue. The second issue is marked as closed, because it's marked as duplicate of the first - Hive issue. So I guess no one is going to look at the closed issue in Cassandra project (and no one will apply the patch) and no one is going to do anything about it on Hive side (because the patch has been submitted to Cassandra). Anyway is there a chance this feature would be available soon? [1] - https://issues.apache.org/jira/browse/HIVE-1434 [2] - https://issues.apache.org/jira/browse/CASSANDRA-913 By the way, I am hoping to achieve lower Hive latency by using the Cassandra, so that I get online processing tool. Is there a chance it would be possible? -- Szymon

Re: Hive + Cassandra?
@Ayon Are you certain that Brisk is a commercial version? Their datasheet states that Datastax' Brisk is an enhanced open-source distribution. While I have no idea what enhanced means (perhaps they offer expertise at a fee), their public github for the project proudly displays an Apache License.
