Love how openly you guys communicate about the management of LW. It's interesting for anyone with an interest in self hosting things to see how you've scaled up. Keep up the good work!
Thanks so much ๐
Is this migrating from pict-rs to object storage or upgrading pict-ra from 0.4 to 0.5?
Object storage. Sorry if that was unclear โค๏ธ
Ah nice congrats on the move
Thanks! It's a lot of work for the behind the scenes stuff, but we have a great team that really cares ๐ผ
Where can I read more about why this is happening?
Actually 2 reasons why. First and most important, this was needed so we can use tooling to detect and remove CSAM material. Secondly, it's because this is more cheap and scalable than having it on disk.
Thank you for doing what you do.
I've heard that being a content moderator is absolutely soul-crushing work. Here's hoping the new tooling lets you automate away the worst of it.
I have no insight into why it's being done in this instance, but object storage is typically used when you want to move away from storing things on your web server with "fixed" storage, and instead store it in an "infinitely" expandable storage system. It is also much easier to manage when you have multiple servers as it's separate and shared.
Right on. This seems relatively important considering pict-rs is the lemmy default. Seems like a change that should be considered for the core repo.
The problem with making S3 config the default is that it would add friction for new admins. If you're just starting to play around with self-hosting Lemmy then it's 100% certain you have a local disk but not nearly as likely that you've got an S3 bucket ready to go. Making S3 the default would force those new admins to either tweak their configs or figure out how to get an S3 bucket before they could get going. Using local disk for images is fine for smaller instances and self-hosts, but for cost and scaling reasons having an option to switch to S3 is really valuable for larger instance like lemmy.world. Only the top 10-20% of instances are likely to really need to make the switch to S3, so Pictrs defaulting to local disk makes sense I think.
While I agree on the technical aspects, I'll say that small instances benefit a lot from s3. My single user instance currently has over 25 Gb of media cache... Object storage (hosted on my NAS ) has been a godsend.
Have you used MinoIO? I've used that before for local S3 and it works quite well.
This is actually what I use. Great piece of software!
Yeah, it's dope.
And surprisingly light on resources (apart from storage space obviously).
What kind, or host?
That we moved to S3 from filesystem
Right, but you said not AWS so I'm curious what either cloud-based S3 service, or baremetal appliance / stack you're using with S3.
Curious as well. Could be Cloudflare R2 since they said they're using Cloudflare elsewhere, and it has zero egress fees. Or something like Minio. Obviously just wild speculation on my part.
Almost seems like he's being cagey about not answering for some reason
I saw "Pictrs Migration" and I thought was about to open a map porn post regarding the movement of ancient Scots.
Guyz, what is Pictr? Is it like Imgur?
Also, [excellent]
Kind of like Imgur, it's a barebones Image hosting server which is what Lemmy uses to serve images uploaded to the instance. It makes it easier otherwise people would need to use things like catbox or imgur itself to host images.
I do feel like support could be better with it though, like if it gave us an interface where we could access our images from our account, or at the very least one for admins.
Was wondering why I couldn't upload anything. Well, 3 more hours to sleep in. Woo!
Congratulations on the move!
Is it amazon s3 storage? How much are we paying for it?
We are not using AWS S3, we try and keep costs down where it makes sense ๐
