[infinispan-issues] [JBoss JIRA] (ISPN-9932) Avoid creating MarshallableEntry instances if no CacheWriter enabled

Avoid creating MarshallableEntry instances if no CacheWriter enabled -------------------------------------------------------------------- Key: ISPN-9932 URL: https://issues.jboss.org/browse/ISPN-9932 Project: Infinispan Issue Type: Enhancement Components: Loaders and Stores Affects Versions: 10.0.0.Alpha3 Reporter: Ryan Emerson Assignee: Ryan Emerson Priority: Major Fix For: 10.0.0.Beta1 The (Dist)CacheWriterIntercepter is enabled if any loader/store is configured. The problem, is that the interceptor assumes that a CacheWriter is always configured. However, it is possible that only a CacheLoader has been configured, in which case when a write command visits the interceptor, MarshallableEntry instances are created unnecessarily in order to call the various PersistenceManager write operations. To avoid unnecessary allocations and the marshalling of key/value/metadata that is never stored, we should ensure that calls to PersistenceManager write methods are only called if a CacheWriter is actually configured.
