[infinispan-issues] [JBoss JIRA] (ISPN-7399) Make visitCommand return an Object instead of an InvocationStage

Make visitCommand return an Object instead of an InvocationStage ---------------------------------------------------------------- Key: ISPN-7399 URL: https://issues.jboss.org/browse/ISPN-7399 Project: Infinispan Issue Type: Task Components: Core Affects Versions: 9.0.0.Beta2 Reporter: Dan Berindei Assignee: Dan Berindei Fix For: 9.0.0.Beta3 Replicated read benchmarks show a significant amount of time spent in {{BasicInvocationStage.toInvocationStage()}}. We can make {{visitCommand}} return an {{Object}} instead of an {{InvocationStage}}, and that return value can be cast to an {{InvocationStage}} when a callback is needed. We can't call {{thenApply()}} etc. directly on an {{Object}}, but we can combine {{invokeNext(ctx, command).thenApply(function)}} into {{invokeNextThenApply(ctx, command, function)}}.
