---------------------------------------
Summary: 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
Reporter: Victoria Markman
Assignee: Jacques Nadeau
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.
