Ignores the old configuration globals
Configuration: sectionsByDB A map of database names to section names
sectionLoads A 2-d map. For each section, gives a map of server names to load ratios. For example: array( 'section1' => array( 'db1' => 100, 'db2' => 100 ) )
serverTemplate A server info associative array as documented for $wgDBservers. The host, hostName and load entries will be overridden.
groupLoadsBySection A 3-d map giving server load ratios for each section and group. For example: array( 'section1' => array( 'group1' => array( 'db1' => 100, 'db2' => 100 ) ) )
groupLoadsByDB A 3-d map giving server load ratios by DB name.
hostsByName A map of hostname to IP address.
externalLoads A map of external storage cluster name to server load map
externalTemplateOverrides A set of server info keys overriding serverTemplate for external storage
templateOverridesByServer A 2-d map overriding serverTemplate and externalTemplateOverrides on a server-by-server basis. Applies to both core and external storage.
templateOverridesByCluster A 2-d map overriding the server info by external storage cluster
masterTemplateOverrides An override array for all master servers.
readOnlyBySection A map of section name to read-only message. Missing or false for read/write.
