Create different user and assign role and privileges. Create a user like guest and grant select only to that user. That way user cannot modify data in specific keyspace or column family. http://www.datastax.com/documentation/cql/3.0/cql/cql_reference/grant_r.html -Vivek On Mon, Jul 21, 2014 at 7:57 AM, Lu, Boying <boying...@emc.com<mailto:boying...@emc.com>> wrote: Thanks a lot ☺ But I think authorization and authentication do little help here. Once we allow an user to read the keyspace, how can we prevent him from writing DB without Cassandra’s help? Is there any way to support ‘read-only’ some keyspace in Cassandra ? e.g. set some specific strategy?
