SubscriptionClient::PrefetchCount Property

Gets or sets the number of messages that the message receiver can simultaneously request.

Namespace: Microsoft.ServiceBus.Messaging
Assembly: Microsoft.ServiceBus (in Microsoft.ServiceBus.dll)

public:
property int PrefetchCount {
	int get ();
	void set (int value);
}

Property Value

Type: System::Int32
The number of messages that the message receiver can simultaneously request.

Remarks

This is a protected member of the abstract SubscriptionClient class. Abstract classes are not meant to be inherited, so protected members should be ignored.

You can use PrefetchCount to fetch multiple messages from the server in the same round-trip. This can be useful in scenarios that need lower latency for receiving existing messages from a queue or subscription. Prefetch can also improve throughput depending upon the scenarios as the number of round-trips to the server are reduced.

Prefetch is disabled by default. You can enable it by using this property on the client. You must set PrefetchCount before receiving the first message.

QueueClient client = factory.CreateQueueClient("queue1");
client.PrefetchCount = 200;

BrokeredMessage message = client.Receive();
