The obvious use case is= the production/analytics datacenter configuration. You don=E2=80=99t want = the production user to be reading/or writing to the analytics datacenter, a= nd you don=E2=80=99t want the analytics user to be reading from the product= ion datacenter. > Although we expect users to get this right on that application level, we = should also be able to enforce this at the database level. The first approa= ch that comes to mind would be to support an optional DC parameter when gra= nting select and modify permissions to roles. Something like {{GRANT SELECT= ON some_keyspace TO that_user IN DC dc1}}, statements that omit the dc wou= ld implicitly be granting permission to all dcs. However, I=E2=80=99m not m= arried to this approach. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscribe@cassandra.apache.org For additional commands, e-mail: commits-help@cassandra.apache.org
