MongoCursor::slaveOkaySets whether this query can be done on a secondary [deprecated] Description
public MongoCursor MongoCursor::slaveOkay
([ bool
$okay = true
] )Warning
This method is deprecated since version 1.5.0. Instead, please use MongoCursor::setReadPreference and Read Preferences. Calling this will make the driver route reads to secondaries if:
Note that you should use this function even if you do not use the automatic routing to secondaries. If you connect directly to a secondary in a replica set, you still need to call this function, which basically tells the database that you are aware that you might be getting older data and you're okay with that. If you do not call this, you'll get "not master" errors when you try to query. This method will override the static class variable MongoCursor::$slaveOkay. It will also override Mongo::setSlaveOkay, MongoDB::setSlaveOkay and MongoCollection::setSlaveOkay. Parameters
Return ValuesReturns this cursor. Errors/ExceptionsThrows MongoCursorException if this cursor has started iterating. ExamplesExample #1 MongoCursor::slaveOkay example
