Talk by Ralph Böhme (SerNet / Samba Team).

Abstract:
Scale-out clustered Samba uses its homegrown distributed database "ctdb" as a storage backend for maintaining coherent fileserver state. "ctdb" predates most, if not all, cloudy distributed NoSQL databases that came to rise on the wings of the likes of Google Bigtable, Amazon Dynamo and Apache Cassandra in the late 2000's to early 2010's.

"ctdb" has worked extremely well for the high performance scale-out NAS use-case, but the emerging shift to the cloud entails serious scalability, elasticity and manageability challenges. So are there alternatives to ctdb? In this presentation we're going to explore Samba's requirements on a distributed database, candidates being Apache Cassandra, Ceph librados, etcd, ScyllaDB, FoundationDB, TiKV and others.

In order to allow rapid prototyping and testing with different database, we've sketched a Python backend for Samba's database abstraction "dbwrap" that calls out to external Python code implementing the abstract interface which allows for quick prototyping and testing. At the end of the presentation we'll share the result of the functional evaluation and some performance metrics.
