 John Ericson | Mic92: et al patch is now merged, backports are set on auto-merge | 00:22:14 |
 Mic92 | @Ericson2314:matrix.org: okay. Hopefully we can have a patch release today if possible. | 02:09:33 |
| John Ericson | Do you think we should patch then try, or try then patch? | 02:10:08 |
| Mic92 | NixOS infra could also apply the patch if someone wants to apply the patch. But I am fairly confident it fixes something at this point | 02:16:06 |
| John Ericson | Yes that's fair | 03:02:28 |
 ElvishJerricco | So, the "redistributable software" RFC seems to be proposing to add ~1-2 TB per month of uploads to the cache. Do we know what the current growth rate is, and if that would be a sustainable size of addition? I know last year a lot of work was done to figure out how to make the cache more financially sustainable and this seems like a big step in the opposite direction. | 14:08:15 |
 hexa (signing key rotation when) | you'd think we'd have a grafana dashboard for that number | 14:11:58 |

| ElvishJerricco | that's user downloads, not hydra uploads, right? | 14:14:01 |
| hexa (signing key rotation when) | that is the space we allocate in the S3 bucket | 14:14:33 |
| ElvishJerricco | oh, that makes more sense | 14:14:42 |
 emily | is the standard number going down from moving things to infrequent access? | 14:15:32 |
| hexa (signing key rotation when) | new stuff enters the standard tier and gets put into IA at some point | 14:16:14 |
| hexa (signing key rotation when) | that is a manual thing iirc | 14:16:20 |
| emily | so i guess in the region of 2–4.5% increase of current cache growth rate? | 14:18:54 |
| emily | monthly | 14:19:01 |
| emily | uh wait no | 14:19:44 |
| emily | had a - instead of a + :) | 14:19:58 |
| emily | so current growth rate is ~6.56 TiB/month, so cache growth size would be 1.15–1.3× current? | 14:20:34 |
| emily | has there been any work or even proposals for things to reduce cache size growth other than "GC everything" that would have anything like a 15–30% impact/ | 14:24:43 |

 vcunat | I've certainly heard proposals like GC everything that's never "been in a channel". | 14:29:58 |
| emily | right, that's what i meant re: GC | 14:34:40 |
