 BMG | What was the guess? | 11:09:44 |
 raitobezarius | I said 5.4M packages data per month | 11:09:51 |
| BMG | Half way there 😉 | 11:10:11 |
| BMG | Looks about 10 millionish a month | 11:10:20 |
| BMG | I can do the month rollup | 11:10:26 |
| raitobezarius | And given that it's narinfo, packages data should be twice that amount or so | 11:10:38 |
| BMG | I can tell you the exact size | 11:11:00 |
| BMG | I have all that info | 11:11:02 |
| BMG | not just for narinfos | 11:11:09 |
| BMG | actually I made a mistake | 11:11:47 |
| BMG | That query is all objects, not just narinfos | 11:11:55 |
| raitobezarius | so I win | 11:12:03 |
| BMG | Let me do a few separate queries here, be more careful | 11:12:07 |
| raitobezarius | But basically the calculation is there's roughly 300k derivations per nixpkgs eval across the 4 architectures, there's 6 channels in parallel (some have common derivations, etc.), so it gives you ~1.8M upperbound over the 6 channels, given that the fast paced channels move every 1-2 days and the slow paced channels move — well — when they want, you can reasonably say there's some interpolation of 1.8M * 3 = ~5.4M derivations happening (and I said every month, but I should have said every 2 weeks or 3 weeks) | 11:14:39 |
 VladimÃr ÄŒunát | With this kind of computation it's easy to make 10x error in the totals. | 11:18:33 |

| BMG | I don't think nars have ever been uploaded uncompressed from poking around the inventory | 11:42:34 |
| BMG | I'll try filtering just for .nar and see | 11:43:10 |
| raitobezarius | It's fine because this more about a lowerbound | 11:44:49 |
| raitobezarius | * It's fine because this was more about a lowerbound | 11:44:53 |
| raitobezarius | so what I'm reading is 2.5M/month-ish narinfos | 11:45:18 |
| BMG | Confirmed, 0 results when looking for keys ending in .nar | 11:45:36 |
| VladimÃr ÄŒunát | Lower bound would be more like: full rebuild (hundreds of thousands jobs) every three weeks, very roughly. | 11:46:04 |
| VladimÃr ÄŒunát | * Lower bound would be more like: full rebuild (hundreds of thousands jobs) every three weeks, very roughly. At least that's how I would think about it. | 11:46:17 |
| VladimÃr ÄŒunát | * Lower bound would be more like: full rebuild (hundreds of thousands jobs) every two weeks, very roughly. At least that's how I would think about it. | 11:46:48 |
