[jira] [Commented] (CASSANDRA-4490) Improve IAuthority interface by
introducing fine-grained access permissions and grant/revoke commands.
[ https://issues.apache.org/jira/browse/CASSANDRA-4490?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13443492#comment-13443492 ]
Jonathan Ellis commented on CASSANDRA-4490:
-------------------------------------------
If we can do this without breaking existing IAuthority implementations, this is probably safe to do in 1.1.x.

> In order to improve IAuthority interface I propose to add the following new permissions: USE, SELECT, CREATE, ALTER, DROP, UPDATE, DELETE, ALL, NONE. And the following new commands to the CQL 3.0 which would give users possibility (with appropriate implementation) to dynamically change user's rights to access system objects:
> GRANT <permission> ON <resource> TO <user> [WITH GRANT OPTION];
> REVOKE <permission> ON <resource> FROM <user_name>;
> LIST GRANTS FOR <user>; // Not 'SHOW' because it's reserved for cqlsh for commands like 'show cluster'
> where <resource> is Keyspace or ColumnFamily (initially, but extendable to indexes or configration options in the future), and <permission> is listed above.
> To keep the system backward compatible with old authorization interface implementations Permission class would include the mappings of the new to old
> permissions:
> READ -> USE, SELECT
> WRITE -> USE, CREATE, ALTER, DROP, UPDATE, DELETE
