> When there are thousands of databases, SHOW DATABASES may take a really long
> time because SENTRY checks if user has any of the following privileges on
> that database for filtering out the database
> DBModelAction.SELECT, DBModelAction.INSERT, DBModelAction.ALTER,
> DBModelAction.CREATE, DBModelAction.DROP, DBModelAction.INDEX,
> DBModelAction.LOCK
> To speedup the authorization checking for this case, Sentry can check only
> the select privilege for SHOW DATABASES and SHOW TABLES based on
> configuration.
