Our experiments show a performance improvement close to one order of magnitude (10x) compared to the state-of-the-art serializable SFaaS systems. I am looking forward to the discussion in Berlin!

We developed a dataflow system, Styx, that provides a Stateful Functions as a Service API, offers serializable guarantees by implementing a deterministic protocol, co-locates state and processing for low latency, and uses the user-transparent coarse-grained fault tolerance.

The first step towards eliminating error-management code in stateful cloud applications was presented today @cidrdb. More to come in the future!

Asterios Katsifodimos@kAsterios

At around 17:30 Amsterdam time at @cidrdb I will be presenting how one can take an object-oriented Python programs and compile it to a dataflow graph and deploy it on streaming dataflow engines. (cidrdb.org/cidr2023/paper…). w @kPsarakis,@wouterdz,@MarioFragkoulis, and @guidosalva.
