NetMessagingBindingExtensionElement.PrefetchCount Property

Gets or sets the number of prefetch.

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

[ConfigurationPropertyAttribute("prefetchCount", DefaultValue = "-1")]
public int PrefetchCount { get; set; }

Property Value

Type: System.Int32
The number of prefetch.

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();
