Pavel Yaskevich commented on CASSANDRA-4490:
--------------------------------------------
It's not only permission but rather resource, permission and grant_option for
now, but it's not final list of fields as it depends on IAuthority
implementation.
> Improve IAuthority interface by introducing fine-grained access permissions
> and grant/revoke commands.

> 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
