Description Ryan Kaldari 2011-12-15 21:25:07 UTC 
Right now, there are several places in CentralNotice where we read data from the master database due to concurrency issues. What we should be doing instead is using wfWaitForSlaves() after doing inserts of data that need to be read immediately, and reading from a slave database.
Comment 1 Brion Vibber 2011-12-16 18:09:58 UTC 
Note that in worst cases, slave delay could be minutes or hours. Is this desirable?
Comment 2 Ryan Kaldari 2011-12-16 18:12:26 UTC 
Oh, I didn't realize that. I assumed it would be a few seconds at the worst. Guess I'll resolve as invalid then. Thanks for the tip!
