Presto RFCs
Presto uses RFCs to propose major features.
Proposing a Feature to Presto
To propose a new feature, you’ll submit a Request For Comments (RFC). This RFC is basically a design proposal where you can share a detailed description of what change you want to make, why it’s needed, and how you propose to implement it.
It’s easier to make changes while your feature is in the ideation phase vs the PR phase, and this doc gives committers an opportunity to suggest refinements before you start code. For example, they may know of other planned efforts that your work would otherwise collide with, or they may suggest implementation changes that make your feature more broadly usable.
Smaller changes, including bug fixes and documentation improvements can be implemented and reviewed via the normal GitHub pull request workflow on the main Presto repo.
RFCs are more suitable for design proposals that are too large to discuss on a feature-request issue, like adding new functionality to Presto, or if a discussion about the tradeoffs involved in a new addition are non-trivial.
If you are unsure whether something should be an RFC or a feature-request issue, you can ask by opening an issue in the main prestodb/presto repository.
How to add an RFC
