OpenTelemetry Enhancement Proposal (OTEP)

Evolving OpenTelemetry at the speed of Markdown

OpenTelemetry uses an "OTEP" (similar to a RFC) process for proposing changes to the OpenTelemetry specification.

OpenTelemetry Enhancement Proposal (OTEP)

What changes require an OTEP

The OpenTelemetry OTEP process is intended for changes that are cross-cutting - that is, applicable across languages and implementations - and either introduce new behaviour, change desired behaviour, or otherwise modify requirements.

In practice, this means that OTEPs should be used for such changes as:

New tracer configuration options
Additions to span data
New metric types
Modifications to extensibility requirements

On the other hand, they do not need to be used for such changes as:

Bug fixes
Rephrasing, grammatical fixes, typos, etc.
Refactoring
Things that affect only a single language or implementation

Note: The above lists are intended only as examples and are not meant to be exhaustive. If you don't know whether a change requires an OTEP, please feel free to ask!

Extrapolating cross-cutting changes

Sometimes, a change that is only immediately relevant within a single language or implementation may be indicative of a problem upstream in the specification. We encourage you to add an OTEP if and when you notice such cases.

OTEP scope

While OTEPs are intended for "significant" changes, we recommend trying to keep each OTEP's scope as small as makes sense. A general rule of thumb is that if the core functionality proposed could still provide value without a particular piece, then that piece should be removed from the proposal and used instead as an example (and, ideally, given its own OTEP!).

For example, an OTEP proposing configurable sampling and various samplers should instead be split into one OTEP proposing configurable sampling as well as an OTEP per sampler.

Writing an OTEP

First, fork this repo.
Copy 0000-template.md to text/0000-my-OTEP.md, where my-OTEP is a title relevant to your proposal, and 0000 is the OTEP ID. Leave the number as is for now. Once a Pull Request is made, update this ID to match the PR ID.
Fill in the template. Put care into the details: It is important to present convincing motivation, demonstrate an understanding of the design's impact, and honestly assess the drawbacks and potential alternatives.

Submitting the OTEP

An OTEP is proposed by posting it as a PR. Once the PR is created, update the OTEP file name to use the PR ID as the OTEP ID.
An OTEP is approved when four reviewers github-approve the PR. The OTEP is then merged.
If an OTEP is rejected or withdrawn, the PR is closed. Note that these OTEPs submissions are still recorded, as Github retains both the discussion and the proposal, even if the branch is later deleted.
If an OTEP discussion becomes long, and the OTEP then goes through a major revision, the next version of the OTEP can be posted as a new PR, which references the old PR. The old PR is then closed. This makes OTEP review easier to follow and participate in.

Integrating the OTEP into the Spec

Once an OTEP is approved, an issue is created in the specification repo to integrate the OTEP into the spec.
When reviewing the spec PR for the OTEP, focus on whether the spec is written clearly, and reflects the changes approved in the OTEP. Please abstain from relitigating the approved OTEP changes at this stage.
An OTEP is integrated when four reviewers github-approve the spec PR. The PR is then merged, and the spec is versioned.

Implementing the OTEP

Once an OTEP is integrated into the spec, an issue is created in the backlog of every relevant OpenTelemetry implementation.
PRs are made until the all the requested changes are implemented.
The status of the OpenTelemetry implementation is updated to reflect that it is implementing a new version of the spec.

Changes to the OTEP process

The hope and expectation is that the OTEP process will evolve with the OpenTelemetry. The process is by no means fixed.

Background on the OpenTelemetry OTEP process

Our OTEP process borrows from the Rust RFC and Kubernetes Enhancement Proposal processes, the former also being very influential on the latter; as well as the OpenTracing OTEP process. Massive kudos and thanks to the respective authors and communities for providing excellent prior art 💖
