“Big data” features coming in PostgreSQL 9.5
I would love to go back to relational, but I can't get over the linear scaling and HA ease of Cassandra and I'm willing to write my applications to work around the data model limitations. Is there any open source SQL database (i.e. "newsql") that can linearly scale with Cassandra's ease right now? I look forward to CockroachDB but it isn't done yet.
