Mostly dealing with table locking and how bugzilla handles most of its |
20 |
queries. If you want more details, look for r2d2, Kingtaco, or jforman |
21 |
(in that order). Another issue was backups were locking up all the |
22 |
tables, so for a matter of an hour or more every day, bugs was just |
23 |
useless because of that. Upstream's 'solution' was to use a db cluster |
24 |
and make the backup on the read-only side. Anyways, I personally don't |
25 |
know a lot of the details, but feel free to ask those people mentioned |
26 |
above. |
