public @Interface Bulkhead

Annotations

Imports

Define bulkhead policy to limit the number of the concurrent calls to an instance.

If this is used together with Asynchronous, it means thread isolation. Otherwise, it means semaphore isolation.

Thread isolation - execution happens on a separate thread and the concurrent requests are confined in a fixed number of a thread pool.
Semaphore isolation - execution happens on the calling thread and the concurrent requests are constrained by the semaphore count.

waitingTaskQueue	back to summary
public int waitingTaskQueue() Specify the waiting task queue. This setting only takes effect on asynchronous invocation, achieved by using `Asynchronous`. The value must be greater than 0. Otherwise, `org.eclipse.microprofile.faulttolerance.exceptions.FaultToleranceDefinitionException` occurs. Returns:int the waiting queue size Annotations @Nonbinding

public int waitingTaskQueue()

Specify the waiting task queue. This setting only takes effect on asynchronous invocation, achieved by using Asynchronous. The value must be greater than 0. Otherwise, org.eclipse.microprofile.faulttolerance.exceptions.FaultToleranceDefinitionException occurs.

Returns:int

the waiting queue size
