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:

I will be presenting our paper in person tomorrow at the 10:35 morning session @AIESConf. Happy to chat about the factors impacting AI developer's practices around algorithmic fairness and broader harms!

Apache Flink won the SIGMOD Systems Award 2023!
Lots of memories from when I joined the team in 2013 as a postdoc in TU Berlin, during the 2nd phase of Stratosphere. Kudos indeed go to the open-source community that made Flink the best stream processor out there!

Our paper "Metadata Representations for Queryable ML Model Zoos" will be presented tomorrow at #DataPerf Workshop #ICML2022.
I'd love to have a discussion on data-centric AI, metadata management for ML life-cycle, and so on!

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!

[SedaG @sedyst]

Dear People, for a project we are doing on the development and deployment of ML engineering pipelines in practice, we are looking to interview Computer Vision engineers from middle & large sized companies in Berlin. Can people help me find contacts? You can also DM me. Merci!

Most Influential Paper talk about GHTorrent by @gousiosg at #msr2022 starts now!

[Asterios Katsifodimos @kAsterios]

(1/2) On Thu at 10:45 CET (@icdeconf), Jim Verhijde (w/ @MarioFragkoulis, @bkarak) will present how internal stream-processor state can be queried efficiently, and a stream processor with queryable state can replace caching/view layers in scalable data processing architectures.

[Asterios Katsifodimos @kAsterios]

Please RT: I am searching for a postdoc (funding for 2-3 years) to work on compiling actor-like programs into transactional dataflow graphs and executing them in dataflow systems. General project motivation in the video below and this preprint:

[Asterios Katsifodimos @kAsterios]

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