Overview

This proposal is for additional functionality to feature source joins to support chained joins, inner joins, and 1-to-many support.

Motivation

This is the most important part of the RFC. It describes the problem domain in detail. Focusing on this will allow reviewers to fully understand why the proposed change is being made, and potentially suggest different/better ways of accomplishing the desired results. The more time we spend on understanding the problem, the better our solution will be.

Funding/Resources

This section will confirm that the proposed feature has enough support to proceed. This would typically mean that the entity making the changes would put forward the RFC, but a non-developer could potentially do so if they are sure they have the funding to cover the change.

Proposed Changes

This is a more detailed description of the actual changes desired. The contents of this section will vary based on the target of the RFC, be it a technical change, website change, or process change. For example, for a technical change, items such as files, XML schema changes, and API chances would be identified. For a process change, the new process would be laid out in detail. For a website change, the files affected would be listed.

Implications

This section allows discussion of the repercussions of the change, such as whether there will be any breakage in backwards compatibility, if documentation will need to be updated, etc.

Test Plan

How the proposed change will be tested, if applicable. New unit tests should be detailed here???
