Building a Rate Limiter using Proxysql

[TUSHAR SINHA]

Hi

I am exploring if it is possible to use Proxysql to build a Rate Limiter.

We want to impose a limit on QPS on master node eg. 2000 QPS and if the QPS goes more than that, the queries should be blocked.

I haven't been able to find documentation for the above feature. Is it possible to build a rate limiter with above features using Proxysql ?

P.S. I found the following Percona blog: Link on Rate Limiter, which describes using “mysql-default_query_delay”  to delay the queries but it is quite different from what we are looking for.

Kind Regards
Tushar
