Interface Bulkhead

All Superinterfaces:
FtHandler
public interface Bulkhead extends FtHandler
Bulkhead protects a resource that cannot serve unlimited parallel requests.

When the limit of parallel execution is reached, requests are enqueued until the queue length is reached. Once both the limit and queue are full, additional attempts to invoke will end with a failed response with BulkheadException.
