Edit : OK so the outage was less brief than expected. The upgrade of the 3GB pictrs database took over 1 hour, and the version 0.4 database is now 14.5 GB... But anyway, it seems to be working alright now!

We will upgrade pictrs today, from 0.3.1 to 0.4.4. This will enable us to switch to S3 storage later on, and is needed for more anti-CSAM tools. Outage should only involve picture uploads, and should be brief.

Awesome that pict-rs has postgres and full s3 support now. Lemmy is getting really scalable!

[-] [email protected] 9 points 7 months ago

I think the postgres support will come in 0.5?

[-] [email protected] 1 points 7 months ago

How will the postgres support look like? They are not storing actual images in the database I hope?

[-] [email protected] 1 points 7 months ago

No. Just like now , they store the metadata there, the images are on disk or S3

[-] [email protected] 1 points 7 months ago

Very good, thank you.

[-] [email protected] 1 points 7 months ago

Ah, right. I was aware of the ability to use S3 for 0.4, but this post made me go check out Asonix's Forgejo. The fact that you can get rid of sled in 0.5 and go fully stateless/scalable is a game changer.

[-] [email protected] 19 points 7 months ago

Yeah we can upload pictures again!

[-] [email protected] 18 points 7 months ago

OK, the pictrs database upgrade is taking it's time... please wait.. ;-)

It's building a 0.4 database, which is already twice as big as the 0.3 one

[-] [email protected] 8 points 7 months ago

It's grown from 3.1 GB to over 8GB and still running...

And that's just his personal collection of feet pics

[-] [email protected] 13 points 7 months ago

Don't tell them about the feetish

[-] [email protected] 13 points 7 months ago

That's not the pictures... The picture take up 1.2 TB.. it's just the database with the metadata about the pictures. (11.8 GB now...)

[-] [email protected] 5 points 7 months ago* (last edited 7 months ago)

I'm curious, how much storage in total is needed for a Lemmy instance like this one currently?

[-] [email protected] 7 points 7 months ago

1.2 TB for pictures and 100GB for Postgres

[-] [email protected] 5 points 7 months ago

For reference I run a pretty small instance. I'm at 34GB for the main database, and about 120GB of media. (Doesn't count backups)

My instance is much, much smaller though. A few hundred users, and probably only a couple dozen actually active.

[-] [email protected] 4 points 7 months ago

Who pays for that s3 storage?

[-] [email protected] 9 points 7 months ago

The people that donate to lemmy.world

[-] [email protected] 6 points 7 months ago

But it’s not in S3 yet. Still on disk.

[-] [email protected] 2 points 7 months ago

I know. Giant database = Giant × 10² amount of Pictures

[-] [email protected] 2 points 7 months ago

Are you manually updating Pictrs or is this included in the new lemmy update?

[-] [email protected] 3 points 7 months ago

Newest update defaults to 0.4, but the latest version is 0.4.4. I don't think there's a significant difference.

But it looks like ruud stayed on 0.3.x until now because there's a pretty serious migration between 0.3.x and 0.4.x
