Subject RE: Hive support to cassandra
Date Thu, 17 Jun 2010 01:35:22 GMT
Just to clarify (since I mentioned HyperTable and Cassandra in that blog post), Facebook's
own integration efforts are currently going into Hive+HBase alone, but for the Hive project
as a whole, we'd be happy to see storage handlers beyond HBase.  Someone from HyperTable has
been working on one and asking questions on hive-user.  At talks I have given, a number of
people have expressed interest in Cassandra, but so far I haven't seen anyone take ownership
on that after the GSoC project was a no-go.

Each technology has its own pros and cons, which I'll stay out of here, but I will say that
I believe Hive can be useful as scaleout data integration/transformation technology even for
stores which are unsuited for data warehousing.

Hey Tom,

I don't want to be rude, but if you're using Cassandra for your data
warehouse environment, you're doing it wrong. HBase is the primary focus for
integration with Hive (see
http://www.cloudera.com/blog/2010/06/integrating-hive-and-hbase/, for
example). Cassandra is a great choice for an OLTP application, but certainly
not for a data warehouse.

Later,
Jeff
