My job has been Database Admin for the past 25 years, still is. But nowadays it's more shifting to infrastructure and automation.

And of course I do some self-hosting.. like lemmy.world and mastodon.world and many others..

Thank you @[email protected] for creating this community!

Systems and software engineer here. I'm curious how the Lemmy project plans on scaling media uploads. It doesn't seem feasible to host on an instance server. Even Reddit had a problem with media over the years and some subs to this day enforce offloading media to third party.

For now it's 2GB. I hope we can use block storage soon. I use Wasabi for mastodon.world

Just Postgres or Postgres + Pics? Could you give me the number for Postgres? I'm thinking in hosting my server but I have concerns abot scalability and costs in the future.

2181	pictrs

It seems a lot for little content. My experience tells me that Postgres is not going to scale well, some sort of NoSQL will be necessary.

Why not? My mastodon DB is 200 GB, works fine.

It depends on many things like the number of tables, the indexes, etc... but Postgres doesn't work well above 1 TB. Anyway, it will take several years to reach that point. Someone will figure out a solution.

Thank you for the info. Do you have any link with the specs of your server, bandwidth, cpu/ram usage, statistics...? Anything that could help me to do the maths.

I'm curious, how have the numbers changed in the last few weeks?

[–] [email protected] 1 points 1 year ago (1 children)

Well we use a new server now, with 32 core/64 threads and 128GB RAM. So quite some more..
