socket.on('disconnect') run with order

[sajjad-fatehi]

hi everyone .
imagine i store my peers in redis for each of my rooms .
user1-> redis.set(roomId,[...redis.get(roomId),user1]
and on disconnect:
redis.set(roomId,[redis.get(roomId).filter(q=>q !== user1)]

for example my 20 users disconnect in same time ... 20 times this code will run in same time and my array will have wrong data

what can i do if i want disconnect event runs one by one ... not in same time

thnks

Hi! Any reason you are not using a Redis Set (with SADD and SREM)?
