Hi there, We have a Python + Websockets + Redis microservice that pulls live stock prices from Binance. Among approx. 450 pairs, micro service should drop unused pairs to reduce CPU & Network overhead. Currently, there is already a incr / decr mechanism to handle drop unused pairs, it is not working efficiently due to highly complex client-side code. Please share your thoughts and previous experience about web apps, websockets, redis and python. Best Wishes Ihsan D. CTO @ karntech
