 @linus:schreibt.jetzt | In reply to @julienmalka:matrix.org
Do we have measures of the total deduplication of an attic cache ? attic doesn't currently have a built-in command for it but it should be pretty easy to get from the db | 08:51:14 |
| @linus:schreibt.jetzt | attic=# select sum(file_size) / (select sum(nar_size) from nar) from chunk;
?column?

| @linus:schreibt.jetzt | so I guess I'm using 20% as much storage for nars as I would be without dedup | 08:53:15 |
| @linus:schreibt.jetzt | *and compression | 08:53:30 |
| @linus:schreibt.jetzt | of course that isn't entirely representative of how much space the cache takes up including file metadata and the database | 08:54:44 |
| @linus:schreibt.jetzt | but I think nars would be the bulk of my binary cache, so that's already a useful number ^^ | 08:55:09 |
