PHP AMQPChannel::qosの例

qos() public method

Specify the amount of data to prefetch in terms of window size (octets) or number of messages from a queue during a AMQPQueue::consume() or AMQPQueue::get() method call. The client will prefetch data up to size octets or count messages from the server, whichever limit is hit first. Setting either value to 0 will instruct the client to ignore that particular setting. A call to AMQPChannel::qos() will overwrite any values set by calling AMQPChannel::setPrefetchSize() and AMQPChannel::setPrefetchCount(). If the call to either AMQPQueue::consume() or AMQPQueue::get() is done with the AMQP_AUTOACK flag set, the client will not do any prefetching of data, regardless of the QOS settings.

public qos ( integer $size, integer $count ) : boolean
$size	integer	The window size, in octets, to prefetch.
$count	integer	The number of messages to prefetch.
return	boolean	TRUE on success or FALSE on failure.
