Not a complaint or a problem, just a discussion.
If we take a look in the image here, I'm being charged for 728GB minutely GB of RAM? What does this mean? What is this a measure of? Why is this number so incredibly high? As well as CPU usage? My graphs don't look drastic whatsoever…

It looks like mongodb is taking a giant chunk of this?

7 months ago
RAM is probably the most expensiveish resource on Railway (and most platforms), your application seems to use quite a bit -between 500mb and 1gb (specially mongo)- which is billed by the minute.

My stupid dependencies… is Mongo not one of your most popular databases? Is this really just hope much it uses?
7 months ago
Yeah, mongo is pretty popular
7 months ago
So nobody can sustain a mongo database under the $5 plan, lol?
7 months ago
Prob PostgreSQL, MySQL and Mongo
7 months ago
Seems to be using 250 and rising, consistently

7 months ago
You can enable serverless to scale it down to zero and then scale back up based on traffic
7 months ago
But yeah, mongo is know for being very mem intensive, together with mysql
7 months ago
I don't really see that being feasable with the amount of time a coldstart would take
7 months ago
Feels weird that nobody can host a very popular database on one of the two plans, especially because it's like, the entire point of this system
7 months ago
I always recommend postgresql if the user wants lower costs
7 months ago
Too late for that 😂
7 months ago
I mean, that's mongodbs fault
7 months ago
I suppose ¯_(ツ)_/¯

250mb is a lot

MongoDB took ~20 cents in one day, * 30 meaning it would be $6 for just one database
7 months ago
@Loudbook this is what i mean (from <#727689277219012669>)

7 cents of ram and 11 cents of cpu
7 months ago
thats from your screnshot
7 months ago
oh I am fairly blind aren’t I
7 months ago
do you run it in a metal region by any chance? when i moved mine to metal the cpu costs went wayyy down
7 months ago
here's the latest today

7 months ago
i'll check
7 months ago
I am not
7 months ago
I’m going to migrate to a closer data center that’s also on metal
7 months ago
yeah definitely give that a try
7 months ago
mongo seems to run better on metal cpus
7 months ago
Is all of this amd64?
7 months ago
yep
7 months ago
Why not arm?
7 months ago
That would be dirt cheap
7 months ago
idk ask railway
7 months ago
lol
7 months ago
🚂
7 months ago
but anyway you can see here on your observability graph, thats an insane amount of cpu for a small db

7 months ago
mine did nonsense like this too before i switched it to metal, i couldnt tell you why it behaved that way but metal cpu good
7 months ago
it now uses so little cpu it barely even registers on the graphs

7 months ago
damn
7 months ago
I’m using 0 now
7 months ago
and a fraction of the RAM too
7 months ago
the memory will creep back up as its used
7 months ago
nvm still most of the RAM as before
7 months ago
yeah
7 months ago
i added --wiredTigerEngineConfigString="cache_size=50M" to mine which stopped it from going above 300 randomly, but it still hovers around 300 and theres not really anything you can do about that
7 months ago
Well yeah, but I don't want every environment connecting to the same one
7 months ago
i switched to using one on railway when mongo killed my free cluster randomly 🥲
7 months ago
uh oh

7 months ago
had a good run tho, that cluster was alive for years
7 months ago
thats strange
7 months ago
nevermind we vibin

7 months ago
is your app using the db a lot?
7 months ago
bipolar db
7 months ago
nope
7 months ago
yeah!
7 months ago
i regularly do that now
7 months ago
railway pro is also
7 months ago
$20/m
7 months ago
i'll keep that in mind if my usage ever grows to $20 naturally
7 months ago
but i'm not paying just for the features
7 months ago
i fear
7 months ago
what are you hosting
7 months ago
do you not get constant random hangs, errors, and invulnerable volumes
7 months ago
and that costs you $110/m?
7 months ago
what the heck
7 months ago
that's a ton of money
7 months ago
you could get a full VPS with a decent CPU for $50/m
7 months ago
and host all of that
7 months ago
meanwhile I can't even deploy a template

7 months ago
due to
7 months ago
"unknown error"
7 months ago
tailscale subnet router
7 months ago
why 😭
7 months ago
:(
7 months ago
idk why they sobbed but looking at my bio may give a hint of why i sobbed
7 months ago
unknown error is weird tho
7 months ago
but maybe worth a separate thread if it persists
7 months ago
deployed that template now and it seems fine for me
7 months ago
you've likely hit the service count limit on the trial plan
7 months ago
Ah well
7 months ago
If I can get my mongodb usage down I’ll consider buying hobby
7 months ago
as a few people have said, that's unfortunately just the reality, mongo uses a lot of memory in comparison to Postgres
7 months ago
Yep I'm not upset
