> The authorization provider retrieves all the privileges for the given set of groups. This could be a huge data set if there are a large number of privileges in the system. A downstream consumer like HiveServer2 will be reading this for each query. This could impact the DB store performance if there are multiple active queries and numerous privilege rules.
> We could consider pushing the filters like DB object name to the policy provider to prune the privilege result set at the source.
