Hello, I'm developing application which uses websockets for chatting feature.
I was wondering what is best way to store all client handles in server side. Every tutorial (eg. this) just says to store in some form of map.
I figured that in large commercial apps list of clients would be rather high and I wondered if storing it on heap is actually valid implementation or if some other solutions like caching dbs like redis are used.
What's your experience with that?
