KVM creators open-source fast Cassandra drop-in replacement Scylla
zdnet.comThe server is AGPL 3: http://www.scylladb.com/opensource/
Client libraries ("drivers") Apache 2.0.
This is fine, but it really should be on the front page.
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?
We target < 1ms latency for 99.9% Some initial results here 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/ Seastar is the underline framework of Scylla
There is an open bug for batch https://github.com/scylladb/scylla/issues/332 hopefully we will fix it shortly.
Latency is great - 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
