             Summary: Reduce number of CompletableFuture allocations during async invocation
                 Key: ISPN-7238
                 URL: https://issues.jboss.org/browse/ISPN-7238
             Project: Infinispan
          Issue Type: Task
          Components: Core
            Reporter: Dan Berindei
            Assignee: Dan Berindei
             Fix For: 9.0.0.Beta1


The current asynchronous invocations allocate a new {{CompletableFuture}} instance (plus a {{UniHandle}}, and a {{ComposedAsyncInvocationStage}}) for every interceptor that calls {{compose()}} or the other {{InvocationState}} methods that add a callback.

We can reduce this by having a list of handlers in each invocation stage, and only creating a new {{CompletableFuture}} when we need to change the {{command}}.
