@domenkozar:matrix.orgDomen KožarI don't think this is going to end well12:39:33
@julienmalka:matrix.orgJulien 7k/mo is still a load difficult to bear for the fondation, no ? If I understand well currently the excess cost with AWS is 6k/mo ? 12:39:53
@flokli:matrix.orgflokliWell, this channel is about binary cache self-hosting ;-)12:40:06
@domenkozar:matrix.orgDomen Kožar7k/mo I can guarantee I can get sponsorship for12:40:10
@domenkozar:matrix.orgDomen Kožar flokli: ok, so where can we discuss the plan then 12:40:24
@domenkozar:matrix.orgDomen KožarI'm fine in any channel :)12:40:29
@flokli:matrix.orgflokliThe foundation currently pays 6k a month out of their own pocket and doesn't want to do this long-term, and the AWS sponsorship coving some more costs is time-limited too, because we need to get our costs down.12:41:07
@flokli:matrix.orgflokliThe number of data in the bucket is also growing, it certainly will if we don't want to GC and don't have the wiggle room to dedup12:41:46
@domenkozar:matrix.orgDomen Kožaryes, we migrate to R2 and we get 6k/mo of sponsors for the foundation and we have the full history12:41:49
@flokli:matrix.orgflokliWe need more than that.12:41:58
@domenkozar:matrix.orgDomen Kožarcache is a common good, we shouldn't just remove stuff if we have a chance of keeping it12:42:01
@domenkozar:matrix.orgDomen Kožarit's 500GB of storage no?12:42:13

it's 500GB of storage no?
Tb
12:42:28
@domenkozar:matrix.orgDomen Kožareh 500TB :)12:42:35
@julienmalka:matrix.orgJulienIt’s going to continue to grow tho12:42:48
@flokli:matrix.orgflokliWe need a more long-term commitment to keep sponsoring this. We need to be certain we can go to cloudflare, and we need to be certain they're ok both with the traffic levels and that staying free12:43:01
@domenkozar:matrix.orgDomen KožarNix is also growing and companies should pay back to keep it alive12:43:04
@domenkozar:matrix.orgDomen Kožarit used to be one company paying for all of this12:43:21
@flokli:matrix.orgflokli We need to be sure we can have some "cloud functions" too, so we can store things differently and more compact, to make this more sustainable too. 12:43:31
@domenkozar:matrix.orgDomen Kožaryeah you have cloudflare workers12:43:43
@flokli:matrix.orgflokliAnd this is now all being discussed a week after we wanted to start the GC.12:43:53
@domenkozar:matrix.orgDomen Kožarwe shouldn't let sunk cost fallacy destroy our history if we can do another plan of saving it12:44:32
@flokli:matrix.orgflokliI don't think workers will be free if we send NAR files through them.12:44:42
@flokli:matrix.orgflokliSomeone needs to do the math, ensure the proposal is feasible, and the sponsors we do come up with can commit a bit long time12:45:06

Well that is one topic where I fully agree with you, but we also must be resilient to situations where we don’t have that solution working. The situation we currently face with GC/AWS cost shows that we are not ready to sustain the costs of hosting the cache with a cloud provider, and we do not own our own data

We don't talk about destroying it, the plan was to put it into glacier, where we can get it back, it's just not immediately accessible, but much cheaper to store.
12:45:43
@domenkozar:matrix.orgDomen Kožarwe own the data, you can transfer it out any time12:45:47
@flokli:matrix.orgflokli* We don't talk about destroying it, the plan was to put it into glacier, where we can get it back, it's just not immediately accessible, but much cheaper to store. Until we have a better place to host it long-term.12:46:01

But because we don’t have our own hardware this is kind of a dream

well that effectively makes it unusuable
