There were never answers to this, so I bring it up here again:
- How were "almost /all/ of the problems the TS have had with replication" "caused by that redundancy and trying to keep it synced"?
Thanks for this question :) - I also want to know.
From my perspective it does not look like this and even the data inconsistencies appear when we have no commons copy on a mysql instance.
And: DaB experimented with federated tables for commons too and we decided to not do this since it does not perform from the start. Probably nowadays when I planned something new in this area (which does not seem to make sense for TS) I'd really give Galera a try - http://codership.com/content/using-galera-cluster
- What limitation will the Toolserver have at some point?
As to #2: From what I've been told this has to do with future sharding plans for the databases, and due to a change in how we'll be doing replication. Of course, I've heard this in passing. For answers to both of these questions you'll need to talk to binasher and/or notpeter on IRC, as they are the ones doing the database work.
Thanks for telling...
