[jira] [Created] (IGNITE-2399) Add asynchronous acquire to IgniteSemaphore

Vladisav Jelisavcic created IGNITE-2399:
-------------------------------------------

             Summary: Add asynchronous acquire to IgniteSemaphore
                 Key: IGNITE-2399
                 URL: https://issues.apache.org/jira/browse/IGNITE-2399
             Project: Ignite
          Issue Type: Improvement
          Components: data structures
            Reporter: Vladisav Jelisavcic
             Fix For: 1.6


Usually a permit acquisition is followed by an action, followed by a release of the permit. A simple enhancement to the existing Semaphore API can be made that enables asynchronous acquire:

<T> IgniteFuture<T> acquireAndExecute(Callable<T> action, int numPermits);

The method would immediately return a future to be later completed by the action's result. Permits are to be released after the future is completed.
