39 Using Timeout with Cache Operations

When many threads access Coherence caches concurrently, callers to Coherence cache operations can be blocked on common locks. This blockage may lead to the accumulation of stuck threads. To help avoid these stuck threads, Coherence uses an interruptible lock so operations can be interrupted after a specified timeout interval. You can use the Timeout API to interrupt and error out the blocking operation after the amount of blocking time exceeds the specified timeout interval.

Here is an example of how to use the Timeout API to interrupt the getCache operation if it takes longer than the given two minute timeout interval:

try (Timeout t = Timeout.after(2, TimeUnit.MINUTES))
     {
     NamedCache cache = CacheFactory.getCache("myCache");
     }
   catch (InterruptedException e)
     {
     // error out getCache() due to timed out.
     }
