-----------------------------------
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.
