Document "Cold starts" for Accelerate

[nikolasburk]

We regularly have users who are confused about cold starts of Accelerate and individual queries taking 5-6 randomly. We should document this behaviour in the Accelerate docs (maybe under "Limitations").

What causes this behavior?

I have been running into this a lot - what can be done about it?

@tylerwithpin @curately could I ask what DB engines/providers you're using?

Hi, I’m using mongoDB hosted on Atlas.

Best, Chris

This issue is caused due to a bug in MongoDB Rust Driver. We have reported the bug with all the details here: https://github.com/mongodb/mongo-rust-driver/issues/1170

MongoDB team has acknowledged the bug and created a Jira issue here: https://jira.mongodb.org/browse/RUST-1994

We are in touch with the MongoDB team and are taking measures to expedite this 🙏

Thanks @nurul3101

The cold start issue with MongoDB + Accelerate should be fixed in prisma version 5.19.0.

Please upgrade to version 5.19.0 to try out the fix 🙏
