How can I rate limit transactions?

Problem Statement

Hi, I'm using sentry self hosted version 24.11.2, with 5K (196K actual but most of them rate limited) error, and 225K transaction rate per hour. My system is kinda powerful, but I'd like to rate limit transactions like errors. Because we are still on a migration to sentry and I'm pretty sure that newcomer projects will make a spike and queues will be lagged. So then, before migrating them, I'd like to add ratelimit for transactions. I've researched several issues here but I couldn't find any proper solution except #1373 but this didn't worked for me. What do you guys suggest?

Solution Brainstorm

NGINX rate limit is ok, but I couldn't understand how can I configure it, I've tried the solution at the issue that I've mentioned above, but it gave 503 Service Unavailable that makes me think about wrong configuration.

Yes, rate limiting on the reverse proxy level is the way to do so. But, you might want to have another layer of reverse proxy that only handles ingestion endpoints only. That means these endpoints: https://develop.sentry.dev/self-hosted/experimental/reverse-proxy/#expose-only-ingest-endpoint-publicly

This might be what you can do.
