AMQPChannel::isConnectedAMQPChannel::qos
(PECL amqp >= Unknown)
AMQPChannel::qos — Set the Quality Of Service settings for the given channel
Beschreibung
$size
, int $count
)
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.
