-----------------------------------

             Summary: PutMapCommand should only write to shared stores on the primary owners
                 Key: ISPN-12031
                 URL: https://issues.redhat.com/browse/ISPN-12031
             Project: Infinispan
          Issue Type: Bug
          Components: Core, Loaders and Stores
    Affects Versions: 10.1.8.Final, 11.0.0.Final
            Reporter: Dan Berindei
             Fix For: 12.0.0.Final


{{DistCacheWriterInterceptor}} uses {{skipSharedStores()}} for single-key write commands and multi-key functional commands in order to write to shared stores only on the primary owner of the key. For {{PutMapCommand}} it uses {{PersistenceManagerImpl.writeMapCommand()}}, which does not distinguish between shared and non-shared stores.

 

In addition to being inefficient, this makes it possible for a backup owner to update the value in the shared store after the primary owner released the lock, potentially out of order with another write operation (especially if the other write operation is single-key, so it only writes to the shared store from the primary).
