A section is collection of wiki databases. A shared database like centralauth is treated like a wiki in that it can be in a section. A query group (sometimes abbreviated to "group") is the set of queries which come from a particular caller or a related set of callers, for example user contributions queries. Query group configuration allows such queries to be directed to particular slaves, to make efficient use of the RAM cache or to avoid having one feature overload the server used by another feature. A cluster is a master DB server and its associated slaves, which are used by ExternalStoreDB for reading and writing article text data. -- Configure bugmail: https://bugzilla.wikimedia.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. _______________________________________________ Wikibugs-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/wikibugs-l
