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!

The main work of my PhD, "Styx: Transactional Stateful Functions on Streaming Dataflows," co-authored by George Christodoulou, @siachamis , @MarioFragkoulis , and @kAsterios , got accepted in @SIGMODConf !

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.

We've been developing a runtime for Transactional Cloud Apps. Here is why we adopted (streaming) stateful dataflow graphs.

After some exciting and productive years at @tudelft and @wisdelft, last Monday I successfully defended my PhD dissertation on tabular schema matching! Always grateful to the people that co-advised me, and especially @kAsterios!

[Asterios Katsifodimos @kAsterios]

We managed to get the complete @tudelft “data” team in @icdeconf in Utrecht, NL.

Here is how it looks like (for now) :)

Searching for a PhD student for my VIDI grant. The team is building a programming model & self-driving streaming dataflow engine for Transactional Stateful Functions.

Apply here by 10th February (and drop me an email): https://t.co/QZjnvf4yIk

[Asterios Katsifodimos @kAsterios]

Took >3 years with @MarioFragkoulis, @SenorCarbone & @vkalavri to write a survey on the evolution of streaming systems in the last 20 years (@VLDBconf J.).

Looking for a single point of reference for all things streaming systems research? It’s here:

We received 🥇best demo paper award 🥇 at @edbticdt2023!

[Andra ionescu @andradenisio]

Tomorrow from 17.30 (EEST) I will present and demo a 🇬🇷 greek themed 🇬🇷 scenario for Topio marketplace, and showcase the search and discovery components of the platform. If you are at @edbticdt2023, drop by the demo session to meet and talk more.

[Kyriakos Psarakis @kPsarakis]

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. (https://t.co/WuQDBrg5uA).

@ckoutras91 @TrlWorkshop Who is Psaraksis?

[Asterios Katsifodimos @kAsterios]

I'm thrilled to to announce that I was awarded the #VIDI grant from @NWONieuws! The funding will allow me to build a transactional actor-like Cloud programming model on top of dataflow systems!

[Asterios Katsifodimos @kAsterios]

We have extended our DEBS paper with:
- discussing transactional #serverless functions and dataflow systems
- a discussion on isolation levels
- more experiments
...
