Description

Suppose you inherit a Drill setup created by someone else (or by you, some time in the past). Or, suppose you are a support person. You want to know which Drill options have been changed from the defaults.

The Web UI conveniently displays all options. But, there is no indication of which might have non-default values.

After the improvements of the last year, the information needed to detect non-default values is now available. Would be great to mark these values. Perhaps using colors, perhaps with words.

For example:

planner.width.max_per_node 200 [Update]

Or

planner.width.max_per_node (system) 200 [Update]

(The Web UI does not, I believe, show session settings, since the Web UI has no sessions. I believe the custom values are all set by ALTER SYSTEM. Otherwise, we could also have a "(session)" suffix above.)

Then, in addition to the [Update] button, for non default values, also provide a [Reset] button that does the same as ALTER SESSION RESET.

planner.width.max_per_node (session) 200 [Update] [Reset]
