The flow for the client 1:
- client connects to server socket, creating "entry" socket to the server called "`server socket 1". This socket is used to transmit data TO the server and receive data FROM the server
- server socket accepts the connection and creates client's entry socket called "`client socket 1". This socket is used to transmit data TO the client 1 and receive data FROM the client 1.
- after sockets are binded: client will send the message with userid (probably signed on for security and integrity) along with chat id (room). The server will parse it and add the client's socket to the room specified in the message. Everything is in memory at this point.

AFAIK there is NO special limitation to the number of client sockets that can be connected apart from memory, cpu, bandwidth etc. There is FileDescriptor limit, which can be extended

===

For scalability - we can just intro some level 4 LB (Transport level TCP/UDP), or as we discussed we can have some "master node" that knows about socket servers and assigns them in a clever way.

UPD: Level 4 Load balancer won't help here, as it does not have mechanism to route by payload (where chat id is located).
So only custom WebSocketServerManager and connect from client directly, or LB with app level, that can distribute by route or payload

fucking oncall. You go sleep 1:30, 2:40 here we are

No 11A :(

Wtf is this sound

It is 16 degrees here in Dublin 🥶

Sorry, guys, probably will not be able to meet with anybody as I am tight in schedule a bit. But next trip - yeah, lets go.

I would say Microsoft office in Prague should learn a bit. Completely different experience. I mean COMPLETELY

Googlers have 3 meals per day, coffee served BY BARISTA, swimming pool, gym, etc in the office directly. This is only what I saw 😁

2 floored bus, feels good

Microsoft Dublin

They have no sweets as I understand. Poor company I am working for, very poor

Also I think we have better screens in Prague. They are big, and there are 2 of them

Last day before going back home brothers

Today we are streaming! Gonna talk about Dublin trip, photos, videos, Google office, Microsoft office and Swe life there
