#Is there a command to clear all the manager caches?

Why would you do that at all?

#

Since my bot is running on several hundred servers the cache gets very full and nightly reports will not work correctly since I hit the RAM limit.

#

But the report always seems to work after a fresh startup.

#

Besides paying more for a virtual machine with more RAM do you have any other ideas?

hard cloud
#

You can fix it using cache.clear() most likely

#

But it looks like a Discord.js problem here, as cache should be freed during low free ram

#

@rain inlet's answer is somewhat good too, but I'm pretty sure that object is used somewhere else too, and it will break stuff. Mine should be fine

summer torrent
#

I'll check it out.

#

I tried limiting the cashes but it definitely broke stuff.

rain inlet
#

yep yours seems a safer way xD

summer torrent
#

I figure if I clear it out it should rebuild itself.

#

Is it necessary to call .clear on each cache?

rain inlet
#

why would you manually empty your cache tho

hard cloud
#

@rain inlet since you're a sponsor can you summon a dev?

#

Cache should be freed on low ram automatically

#

At least this is my guess since I see memory usage spiking.

rain inlet
#

have you tried limiting your caches?

summer torrent
#

And the report runs perfectly fine after a fresh launch of my app.

hard cloud
#

What is this report all about?

summer torrent
#

I tried limiting some of them, but I must have limited too much and crashed the app.

Here are the different caches I was looking at:

hard cloud
#

You should almost never use cache.get

next violet
#

That is absolutely untrue

#

Spread nonsense elsewhere

#

@summer torrent i think you may just need to go through each single cache collection and use collection.clear() im not sure tho so dont take my word for it

rain inlet
#

if you really want to clear all those caches yeah you'd have to go through every single one of them there's no method that clears all of them

Those I believe are all the caches. I wish I could find recommended settings for them.

Take for example the MessageManager cache. Does each server that installs my bot have their own message cache?

#

Or is this one cache for all servers?

rain inlet
#

for all servers

hard cloud
#

I'm not sure, but maybe client.guilds.cache.clear() may be enough

#

The GC will take care of the rest

summer torrent
#

Got it.

#

I'll give that a shot.

#

I'm not too familiar with the cache so I appreciate the input.

#

Learning as I go on this one.

rain inlet
#

yeah each channel object has a messagemanager

#

which then has the cache

summer torrent
#

eek...so I would have to clear the cache from every channel that my app can see?

rain inlet
#

yes yikes

summer torrent
#

oh boy...maybe I would look into limiting that cache instead lol

#

I'll have to see if I can find more details on limiting caches.

rain inlet
# 
client.channels.cache.forEach(c => {
    if (c.isText()) {
        c.messages.cache.clear()
    }
})```
#

you'd have to do smth like this 💀

summer torrent
#

Suppose my app can see hundreds of channels, maybe thousands...lol

rain inlet
#

200*<ChannelManager>.cache.size() is your amount of cached message objects

#

then just think about it... do you really need to have these messages cached?

summer torrent
#

Right

rain inlet
#

I have it set to 20 per channel shrug but idk what your bot does so

summer torrent
#

That's might be the cache to go after first. Seems like that one could bloat quickly.

rain inlet
#

yesyes

#

and disable the ones you'll never access

#

like idk

#

StageInstanceManager

summer torrent
#

Sounds good! I'll play with it and see what happens! Thanks for your help and thoughts!

rain inlet
#

yep np

#

good luck
