We are seriously evaluating both Cassandra and HBase in our
organization. We are very pleased with the performance and ease of use
of Cassandra and will start the same exercise with HBase soon. However
some people in the organization feel that HBase has a larger comunity
adoption. I understand that Cassandra has been deployed within Facebook
also at Digg and Rackspace. I also went through the survey that
Jonathan had conducted a few weeks back.
I am interested in
hearing from those of you if there are any who have ditched HBase for
Cassandra. If so why? Also, perhaps this is not a question for this
list, is HBase used for real timish applications and if so any ideas
what the largest deployment is. It would help me in swaying the folks
towards Cassandra. Any help would be appreciated.
