Remove extra thread in BlockingTaskAwareExecutorServiceImpl ----------------------------------------------------------- Key: ISPN-11561 URL: https://issues.redhat.com/browse/ISPN-11561 Project: Infinispan Issue Type: Sub-task Components: Core Reporter: Will Burns Assignee: Will Burns Priority: Major Fix For: 11.0.0.Dev04 The BlockingTaskAwareExecutorServiceImpl spawns a controller thread to handle requests. We should be able to remove that thread and instead use an idea similar to rxjava with processing in a single invoked thread instead as the operations it spawns are non blocking. We should also optimize calls to avoid O(n) calls like size.
