  This sounds like awesome news! - How it compares to Cassandra regarding latency? - How is the client API? Does it support lock free communication? Can you send things to nodes in batches?

    Latency is great - http://www.scylladb.com/technology/cassandra-vs-scylla-latency-benchmark/ http://www.scylladb.com/technology/cassandra-vs-scylla-laten... and we promise to improve it further. The client API is CQL. We have thrift too but it's not mature enough. We'll invest in thrift per community feedback

    We target < 1ms latency for 99.9% Some initial results here http://www.scylladb.com/technology/cassandra-vs-scylla-latency-benchmark/ http://www.scylladb.com/technology/cassandra-vs-scylla-laten... DB API (CQL) is Cassandra compatible, so clients does not have to change. For more on the lock free communication see http://www.seastar-project.org/ http://www.seastar-project.org/ Seastar is the underline framework of Scylla There is an open bug for batch https://github.com/scylladb/scylla/issues/332 https://github.com/scylladb/scylla/issues/332 hopefully we will fix it shortly.

  The server is AGPL 3: http://www.scylladb.com/opensource/ http://www.scylladb.com/opensource/ Client libraries ("drivers") Apache 2.0. This is fine, but it really should be on the front page.
