I’m trying to put together a plan for a library that I am working on whereby I need to provide an interface that allows the client to asynchronously call out to external APIs (HTTP endpoints in this case). I also need to make sure that this is rate limited to adhere to the rate limiting on the exter…

Discord published a blog post covering how they use genstage to buffer calls to Firebase APIs. It has some code examples as well as performance statistics.

That looks awesome thanks @mechabyte . I will have a proper read through when I get home from work.

In addition to the discord article linked above, I came across this talk which is probably the best explanation and demo of an end to end genstage setup I have come across. Well worth a watch (especially if you’re new to genstage)

Nice. haven’t seen this talk yet. :slight_smile: Q: Is there use case for GenStage for example for simple CRUD API calls for users, projects, etc. Just for simple data requests?

From my basic understanding so far I would say yes there is. Genstage looks to be a great fit for when you’re having to deal with external forces such as networking for example (rest apis, databases, etc…). It allows the workers to dictate how much work they are given which prevents the likely impo…

Ok, this sounds cool. Is there any example of how you write GenStage server for example for User CRUD module? I don’t have an idea how you manage those actions in GenStage server.

I would suggest definitely take the 40 minutes to watch that talk as that will probably answer your question better than I could. The demo is a restruant simulation which demonstrates the full cycle of tables placing an order (that’s processed through genstage) and then receiving thier food all wit…

Ok, super. Added to my tomorrows to do list. Thank you! :thumbsup:

Here’s a simple example of a multi-stage pipeline. I found Jose’s talk really helpful (linked in example).

Thanks @wfgilman , that’s a very interesting example. I haven’t seen any others that are dynamically starting and linking multiple stages like that.
