I’m delighted to announce today that we’ve raised $60M in Series C funding at @MaterializeInc! We’ve now raised a little over $100M since inception in our goal to make every business real-time.

We’re super excited to announce the release of Materialize 0.9! We’ve been hard at work these past few months smoothing out some rough edges, and hardening Materialize for production.
materialize.com/release-0-9 + 🧵 for highlights about the release!

I had a fun time chatting with @KostasPardalis and @EricDodds on the Data Stack Show - we talked about Materialize, databases, and where we think this whole streaming thing is going!

I enjoyed speaking with @MaterializeInc user Jean-Francois Perreton, who heads the Algo Quant team at Kepler Cheuvreux. Check out our conversation to learn how they’ve used Materialize to build their real-time trading algorithms platform: youtube.com/watch?v=xEbXZcnD…
For last Skunkworks Friday at @MaterializeInc I created a prototype sink for the Materialize CDC format.
I wanted to see if I could daisy chain multiple materialized instances to replicate views. Turns out it works! 😅

📣📣📣 I started a blog. In my first blog post I talk about a question I had for a long time on Fault Tolerance in Stream Processing Systems. Here it goes: github.com/kl0u/blog/blob/ma…
I hope you enjoy it!
Today was my last day with @VervericaData.
Over the years, I had the chance to work with many wonderful people and made some good friends. 😍
I will miss working with all of you but it's time for me to do something else. 🖖

The bigger the project, the harder it gets to introduce changes. It took years but finally @ApacheFlink has a consistent coding style for Java 🥳 A tiny 1.4M PR...

I think I'll use this election to explain event time vs. processing time next time I teach stream processing 😎
There's now a video of my recent talk on unified APIs for batch and stream processing on Apache Flink: youtu.be/z9ye4jzp4DQ.
I also uploaded the slides, in case anyone is interested. You can check those out on my "blog": github.com/aljoscha/blog/blo…. 😅
#ApacheFlink
I'm giving a talk later today about how we unified the APIs for stream and batch processing on #ApacheFlink. You can still sign up for the conference, it's free! I'll also make the slides available later, though, in case you miss it.

Just added a new blog post introducing the Apache Flink Stateful Functions Rust SDK: github.com/aljoscha/blog/blo…. It's also interesting if you want to learn about Statefun internals or write your own language SDK, which I can highly recommend.

Just published a #golang SDK for @ApacheFlink Stateful Functions. The plan is to donate this to the Apache project but right now I could use help from more experienced go devs. If you know go or are interested in stateful serverless, please take a look. github.com/sjwiesman/statefu…
We're thinking about removing union list state from #ApacheFlink: lists.apache.org/thread.html…. I'd be very interested to see how many people are using this if any. Please tweet at me if you have a use case that needs it.
