             Summary: Async Cache Writer is blocking
                 Key: ISPN-11727
                 URL: https://issues.redhat.com/browse/ISPN-11727
             Project: Infinispan
          Issue Type: Enhancement
          Components: Loaders and Stores
            Reporter: Will Burns


The current AsyncCacheWriter is blocking on a few different levels.

It first has a lock to add a modification to its queue, which is able to be configured by the end user. It may even be possible to configure a value so low that if a bulkUpdate is done that is larger than the configured value it may hang (needs to be confirmed).

However this lock can and will block if an async update takes too long and the queue is full of writes. We should at least return a future that is complete when the value is written to the queue instead.

We may want to even use something like https://github.com/IBM/java-async-util with their AsyncSemaphore to handle this queueing in a non blocking way.
