This sounds wonderful! And it validates many of my own thoughts. :)

Your product would align nicely with these DAG recomputation engines like Fluvio and Temporal (Seattle).

Well Noria implements MySQL protocol, so if your system targets MySQL, you could run DataSQRL on Noria!

Exactly, there are so many amazing dataflow engines, stream processors, and databases out there. We are not competing with those.

We are trying to "compile away" all of the data plumbing code you have to write to integrate those systems into your application, so that it becomes easier to use them.

MySQL support in DataSQRL is definitely on the short-list.

You support JDBC, so JDBC->MySQL Protocol->Noria should work for some definition.

My one minor nit is the creation of a new language. How does ChatGPT4 handle in reading it or writing it? It is possible to teach it a new language inside the prompt but you run out of context window.

I am not being glib, but I mapped out pretty much this exact product. The crux of your success will be in the schema discovery and versioning your schema, data and flows in a way that be tractably upgraded and downgraded.

You are totally right. We did not want to create a new language and we are trying to keep it as close to SQL as possible. The problem is that SQL lacks streaming constructs you need for temporal joins or creating streams from relational tables. Jennifer Widom's group at Stanford did a lot of work on this (e.g. [1]). We are adding their operators to SQL in a way that is hopefully "easy enough". The rest is just syntactic sugar.

But we are not tied to SQRL and totally open to ideas for making the language piece less of a hurdle.

GPT4 is surprisingly good at writing SQRL scripts with few-shot learning.

You are also right on the schema piece. We are trying to track schemas like dependencies in software engineering. So you can keep them in a repo and let a package manager + compiler handle schema compatibility and synchronization. https://dev.datasqrl.com/ is an early prototype of the repository idea.
