Interface OptionManager

All Superinterfaces:

Iterable<OptionValue>, OptionSet

All Known Implementing Classes:

BaseOptionManager, FallbackOptionManager, FragmentOptionManager, InMemoryOptionManager, QueryOptionManager, SessionOptionManager, SystemOptionManager

public interface OptionManager
extends OptionSet, Iterable<OptionValue>

Manager for Drill options. Implementations must be case-insensitive to the name of an option. The options governed by an OptionManager fall into various categories. These categories are described below.

• Local: Local options are options who have a value stored in this OptionManager. Whether an option is Local to an OptionManager or not should be irrelevant to the user.
• Public: Public options are options that are visible to end users in all the standard tables and rest endpoints.
• Internal: Internal options are options that are only visible to end users if they check special tables and rest endpoints that are not documented. These options are not intended to be modified by users and should only be modified by support during debugging. Internal options are also not gauranteed to be consistent accross patch, minor, or major releases.
