Helper class used for automatically re-using IDatabase connections and lazily establishing the actual...

Class to handle database/schema/prefix specifications for IDatabase.

Interface to a relational database.

This class is a delegate to ILBFactory for a given database cluster.

getClusterName()

Get the name of the overall cluster of database servers managing the dataset.

getMaxLag()

Get the name and lag time of the most-lagged replica server.

const CONN_UNTRACKED_GAUGE

Yield an untracked, low-timeout, autocommit-mode handle (to gauge server health)

hasOrMadeRecentPrimaryChanges( $age=null)

Check if this load balancer object had any recent or still pending writes issued against it by this P...

getLagTimes()

Get an estimate of replication lag (in seconds) for each server.

getServerType( $i)

Get the RDBMS type of the server with the specified index (e.g.

const GROUP_GENERIC

The generic query group.

getServerConnection( $i, $domain, $flags=0)

Get a DB handle for a specific server index.

getReaderIndex( $group=false)

Get the specific server index of the reader connection for a given group.

resolveDomainID(DatabaseDomain|string|false $domain)

const DOMAIN_ANY

Domain specifier when no specific database needs to be selected.

const DB_REPLICA

Request a replica DB connection.

const CONN_TRX_AUTOCOMMIT

Yield a tracked autocommit-mode handle (reuse existing ones)

setTableAliases(array $aliases)

Make certain table names use their own database, schema, and table prefix when passed into SQL querie...

const CONN_SILENCE_ERRORS

Yield null on connection failure instead of throwing an exception.

setTempTablesOnlyMode( $value, $domain)

Indicate whether the tables on this domain are only temporary tables for testing.

setDomainAliases(array $aliases)

Convert certain database domains to alternative ones.

getServerCount()

Get the number of servers defined in configuration.

getLocalDomainID()

Get the local (and default) database domain ID of connection handles.

getServerInfo( $i)

Return the server configuration map for the server with the specified index.

waitForPrimaryPos(IDatabase $conn)

Wait for a replica DB to reach a specified primary position.

setTransactionListener( $name, ?callable $callback=null)

Set a callback via IDatabase::setTransactionListener() on all current and future primary connections ...

hasPrimaryChanges()

Whether there are pending changes or callbacks in a transaction by this thread.

getPrimaryPos()

Get the current primary replication position.

getConnection( $i, $groups=[], string|false $domain=false, $flags=0)

Get a lazy-connecting database handle for a specific or virtual (DB_PRIMARY/DB_REPLICA) server index.

getMaintenanceConnectionRef( $i, $groups=[], $domain=false, $flags=0)

Get a DB handle, suitable for migrations and schema changes, for a server index.

explicitTrxActive()

Determine whether an explicit transaction is active on any open primary connection.

getReadOnlyReason()

const DB_PRIMARY

Request a primary, write-enabled DB connection.

getConnectionInternal( $i, $groups=[], $domain=false, $flags=0)

hasReplicaServers()

Whether there are any replica servers configured.

hasStreamingReplicaServers()

Whether any replica servers use streaming replication from the primary server.

pingAll()

getServerName( $i)

Get the readable name of the server with the specified index.

getServerAttributes( $i)

Get basic attributes of the server with the specified index without connecting.
