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!
📜Excited to see that our paper got accepted to @AIESConf ! With @MireiaYurrita, @yangjiera, @UjLaw, we investigated the factors that fragment AI developers' practices when handling algorithmic harms in AI models, through a qualitative study with 30 practitioners.#AIES💻+⚖️+🧑💻

I am searching for two PhD students and one postdoc for my VIDI grant. We are building a programming model & self-driving dataflow engine for Transactional Stateful Functions.
For PhD apply here by 15th July: tudelft.nl/over-tu-delft/wer…
Postdoc: drop me an email!

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!
Big news: @ApacheFlink receives this year's @sigmod Systems Award! The project was started at TU Berlin back in 2009 but it would be nowhere today (feature and adoption-wise) without its awesome community. Thanks to everyone who contributed to Apache Flink! 👏🙏

We have an open research internship position on the design of deep GNNs! Please help spread the word!
#GNN #GraphMachineLearning #MachineLearning #GraphMining
An internship position is open to work on Deep Graph Neural Networks at @centralesupelec, @Inria_Saclay, and @telecomparis. The intern will be jointly supervised between @frank8m and myself. Please spread the voice 😄. For further details please see: drive.google.com/file/d/1bLL…

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!
NWO has awarded 101 experienced researchers a #Vidi grant of 800,000 euros. This will enable them to develop their own innovative line of research over the next five years and set up a research group. Read more nwo.nl/en/news/101-researche…

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!

(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.

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:

I uploaded my talk at #flinkforward here:

TL;DW; Building scalable cloud apps is a pain in the butt. To scale out, people actually build parallel dataflow systems without knowing it. This needs to change. We are working on it.

We have extended our DEBS paper with:
- discussing transactional #serverless functions and dataflow systems
- a discussion on isolation levels
- more experiments
...
Here: doi.org/10.1016/j.is.2022.10…
With Martijn de Heus @kPsarakis @MarioFragkoulis
We received the🏆 Best Paper Award at @ACM_DEBS! 🏆
For implementing transactions (2PC and Sagas) on @ApacheFlink's Serverless Functions (@statefun_io).
Great work by Martijn De Heus, @kPsarakis and @MarioFragkoulis!
