Hi, If I understand correctly, the new names are simply aliases that point to either Zedler or Yarrow. For example, the following all refer to the same physical server: * zedler * sql * sql-s2 * commonswiki-p.db.ts.wikimedia.org * enwiktionary-p.db.ts.wikimedia.org As do these: * yarrow * sql-s1 * sql-s3 * enwiki-p.db.ts.wikimedia.org * jawiki-p.db.ts.wikimedia.org It's just a case of how we refer to them in our code. (IMHO I like the new database-specific aliases) Cheers, Tangotango On Jul 14, 2007, at 2:35 AM, Sean Whitton wrote: _______________________________________________ Toolserver-l mailing list Toolserver-l(a)lists.wikimedia.org http://lists.wikimedia.org/mailman/listinfo/toolserver-l

Sean Whitton: this is because these sets are decided by the database layout at Wikimedia's cluster, not us. Wikimedia has three separate master/slave groups, s1, s2, and s3 (there's also s2a and s3a, but those don't matter to us). we don't need that much capacity, so s1 and s3 are both on yarrow. but, if you use sql-s1 and sql-s3 properly, your code will still work if we add a third server in future. - river. _______________________________________________ Toolserver-l mailing list Toolserver-l(a)lists.wikimedia.org http://lists.wikimedia.org/mailman/listinfo/toolserver-l
