Replace CompletionStageToPublisher with CompletionStageToSingle --------------------------------------------------------------- Key: ISPN-10948 URL: https://issues.jboss.org/browse/ISPN-10948 Project: Infinispan Issue Type: Sub-task Components: Core Reporter: Will Burns Assignee: Will Burns Priority: Major Fix For: 10.1.0.Beta1 We shouldn't ever need to convert a CompletionStage to a Publisher as this implies multiple values. Instead we should always convert to a Single at worst case. This should provide less overhead as the processing for Single is much less complex then Publisher.
