Description

Author: bhartshorne

Description:
The externalLoads array (in db.php) specifies a number of clusters that hold external store data. Only one of those clusters (set by wgDefaultExternalStore) accepts writes. For all the others, they are static read only databases, and replication lag should not matter. When accessing those clusters, the mAllowLagged flag should be set in the LoadBalancer class object.
