> Expose only "productized" system/session configuration parameters

>
> Key: DRILL-2623
> URL: https://issues.apache.org/jira/browse/DRILL-2623
> Project: Apache Drill
> Issue Type: New Feature
> Components: Execution - Flow
> Reporter: Victoria Markman
> Assignee: Jacques Nadeau
> Fix For: 1.2.0
>
>
> This is an enhancement request to expose only well tested and useful
> parameters to the end user.
> For example, we don't want to allow all users to change internal
> configuration parameters, like exec.min_hash_table_size or enable features
> that are not ready for prime time ( store.parquet.enable_dictionary_encoding
> for example).
> However, sometimes in order to achieve optimal performace some configuration
> fiddling will be absolutely necessary. We can allow different users with
> different privileges have an ability to change settings.
> One of the proposals to achieve this is to create a view on top of
> sys.options that will be created on drills start up and have privileged
> access
> a) to the information in the view - show only things that particular user is
> allowed to see
> b) have privileged access to "ALTER SYSTEM/SESSION" commands.
