fetchRecommendedShardCount

I want to know how this works, since shard_id = (guild_id >> 22) % num_shards, hinting that we can't anticipate guildsPerShard. There's multipleOf as well, how do these terms link together in a single expression?

The former expression is just Discord's way of assigning guilds to shards

Multiple of just ensures that the number of shards is divisible by that multiple while being greater or equal to the actual recommended shard count

Like if Discord says you should have 12 shards, but you want it to be a multiple of 5, the expression would round up to 15 shards

I'm aware of the first two statements; when might multipleOf be of use if not the shard number given by Discord? Also, if additional shards are spawned wouldn't it cost the user more resources than what would actually be in use?

As for guildsPerShard I guess that 1000 was the per shard limit back then

• multipleOf is needed for big bot sharding where you can only have the shardCount be a multiple of the concurrency identify limit
• and no, 1000 is the amount of guilds per shard that discord recommends to have when starting up the bot so it has enough room for guilds your bot joins while running

2. That's nice
3. "concurrency identify limit" means? max_concurrency field in the session start limit?

Yes
