> 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:

> 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.
