public void UpdateConcurrency(int maxConcurrentCalls);member this.UpdateConcurrency : int -> unitPublic Sub UpdateConcurrency (maxConcurrentCalls As Integer)Parameters
- maxConcurrentCalls
- Int32
The new max concurrent calls value. This will be reflected in the MaxConcurrentCalls property.
Remarks
When reducing concurrency, cancellation will be requested for in-progress message handlers that exceed the new concurrency limit via their associated CancellationToken. There is no guarantee as to which handlers will be cancelled. Handlers should observe the cancellation token passed via CancellationToken and handle cancellation gracefully to avoid incomplete processing. The cancellation is cooperative; handlers that do not observe the token will continue to run until they complete. When increasing concurrency, the change takes effect immediately by allowing additional concurrent message handlers.
