I'm a developer of DBSP. Our repo now lives here: https://github.com/feldera/dbsp/. And here is some more benchmarking data vs Flink and Beam: https://github.com/feldera/dbsp/tree/main/benchmark.

See feldera.com for more info.

Thank you!

Really happy to see all the activity at the new repo. For a while there I thought the project was dying...
