Yesterday, Kate told me that the problem with replication from the Asian
cluster is that mysql can only connect to one replication master. I have
googeled a bit, and it appears that that is not true (at least for MySQL
Multiple-master replication is possible, but raises issues not present
in single-master replication. See Section 6.15, “Auto-Increment in
talks about problems with auto-increment keys, which should not affect
us, since databases replicated from each master would be disjunct.
I have not dug deeper yet, but I'm probably not the best person to
fiddle with that anyway.
I hope one of you can have a look at it - having no data from the Asian
wikis on the toolserver is a serious problem.
