| Carsten Kragelund Jørgensen | Is there a preferred way to get bulk data from hydra? I'm looking to build out a dataset of build failures, but don't want to be rude and just have a script running 24/7 downloading individual build results. | 21:34:02 |
 hexa | there are already various platforms that provide that information | 21:34:43 |
| hexa | https://zh.fail/
https://malob.github.io/nix-review-tools-reports/
and a tool by Fernando Rodrigues which I don't remember the name for that groups by error | 21:35:21 |
| Carsten Kragelund Jørgensen | zhf is essentially what i be looking for, though i am more interested in historical failures stats | 22:25:29 |
| hexa | infra can provide you with selective database dumps if you can point to what you need | 22:32:09 |
 Fernando Rodrigues | uhh, that's not mine? | 23:02:02 |
| hexa | oops, sorry | 23:02:20 |
| Fernando Rodrigues | I think, I don't remember doing anything with hydra? | 23:02:21 |

| hexa | 😬 | 23:04:21 |
| hexa | off by one sigma, I guess | 23:04:27 |
| hexa | we are very interested in a list of packages that have been failing for a long time | 23:07:56 |
| hexa | so we can remove them, disable them on certain platforms, save us constant rebuild churn | 23:08:14 |
| Carsten Kragelund Jørgensen | Ideal would be a dump of the builds from the nixpkgs:unstable builds from like 2021 or so, and including the build logs if possible.
But I also wouldn't be opposed to expanding out the scope to do any extra analysis that would help the team.
As for transfer of the dumps, I can provide access to an s3 bucket in whatever region would be local, or whatever is easier for you guys. | 23:14:24 |

| hexa | build logs are not in the database I'm afraid | 23:25:56 |
| hexa | they are on cache.nixos.org | 23:26:01 |
| Carsten Kragelund Jørgensen | oh they are, i somehow completely missed the different domain when manually inspecting, yeah, i can handle backfilling the logs as needed from the cache after having filtered down to what i personally need then, thats no problem. | 23:31:51 |

| adamcstephens | How big are the database dumps? | 13:39:56 |
| hexa | well, not full dumps, selective dumps | 13:46:38 |
| hexa |
zroot/pg 466G 1.17T 393G /var/lib/postgresql
| 13:46:51 |
| adamcstephens | selective because there are some user/auth tables? | 13:48:52 |
| hexa | for example | 13:52:29 |
| hexa | and not all data is needed for every purpose | 13:52:37 |
