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

             Summary: Cassandra Cache Store is read-only by default
                 Key: ISPN-3520
                 URL: https://issues.jboss.org/browse/ISPN-3520
             Project: Infinispan
          Issue Type: Bug
          Components: Loaders and Stores
    Affects Versions: 6.0.0.Alpha4, 5.2.6.Final
            Reporter: Giovanni Mels
            Assignee: Mircea Markus


It is impossible to store any data in the Cassandra cache store, because it is created as read-only, even when specifying {{ignoreModifications = false}}. See the attached test case:

I tracked this bug down to the {{create}} method in {{CassandraCacheStoreConfigurationBuilder}}
{code}
   @Override
   public CassandraCacheStoreConfiguration create() {
      List<CassandraServerConfiguration> remoteServers = new ArrayList<CassandraServerConfiguration>();
      for (CassandraServerConfigurationBuilder server : servers) {
         remoteServers.add(server.create());
      }
      return new CassandraCacheStoreConfiguration(autoCreateKeyspace, configurationPropertiesFile, entryColumnFamily,
            expirationColumnFamily, framed, remoteServers, keyMapper, keySpace, password, sharedKeyspace, username,
            readConsistencyLevel, writeConsistencyLevel, autoCreateKeyspace, sharedKeyspace, purgerThreads, framed,
            autoCreateKeyspace, TypedProperties.toTypedProperties(properties), async.create(), singletonStore.create());
   }
{code}
Note how {{autoCreateKeyspace}} is used in stead of {{purgeInternal}} and {{ignoreModifications}}, so if you explicitly set {{autoCreateKeyspace = false}} you can work around the issue.
This is tested on 5.2.6, all versions from 5.2 on have the same error.
