We have a bunch of services which orchestrate long running workflows so temporal is quite interesting to me. I've been lurking in the temporal slack for a while (and before that in the cadence slack).

Would be interested to know what kinds of things you're using it for/what scale/which language client?

I work for an accounting company with a few hundred workers, who every month had to submit a lot of files, and collect a lot of documents from human-only websites.

About two years ago I built a custom workflow engine in python where I had a few primitives (filesystem, database access, browser (puppeteer scripts), etc), and would define a workflow using those primitives using a YAML DSL.

In a couple weeks I ported the whole thing to Temporal (Java client), where each of those primitive groups is a different activity, which runs in a separate worker. I have a browser worker, which runs in the only servers that have internet access, a filesystem worker, which is on a Windows machine serving as an entrypoint to the company's windows filesystem, a database worker, etc.

This is all very scalable, and I can run as many of each worker and the engine itself as I like.

Currently the scale is not too big though. I launch a few "main" workflows in certain days of the month that will then spawn up to 4 thousand child workflows which run simultaneously with no problem.
