> Policy validation: resource uniqueness: store resource signature of a policy
> in database for faster check
> ---------------------------------------------------------------------------------------------------------

> Key: RANGER-359
> URL: https://issues.apache.org/jira/browse/RANGER-359
> Project: Ranger
> Issue Type: Sub-task
> Reporter: Alok Lal
> Assignee: Alok Lal
> Fix For: 0.5.0
>
>
> Currently we iterate over all policies for a service, a generate its resource
> signature and use that to enforce uniquness. This can be computationally and
> space intensive if, say, there are several policies for a service or
> create/update of policies happens frequently. The resource signature of a
> policy could be kept in the database and kept up to date as resources change.
> Then a database level search could allow for doing this check cheaply and
> robustly.
> Another way to reduce the space complexity could be to allow policy search
> command to return an Iterator instead of the collection of policies itself.
> This has some other challenges but is listed here for completeness.
