# Experimental Features
|
||
|
|
|
||
|
|
The SDK contains features that have not yet stabilized in the OpenTelemetry specification.
|
||
|
|
These features are added to the OpenTelemetry Go SDK prior to stabilization in the specification so that users can start experimenting with them and provide feedback.
|
||
|
|
|
||
|
|
These feature may change in backwards incompatible ways as feedback is applied.
|
||
|
|
See the [Compatibility and Stability](#compatibility-and-stability) section for more information.
|
||
|
|
|
||
|
|
## Features
|
||
|
|
|
||
|
|
- [Resource](#resource)
|
||
|
|
|
||
|
|
### Resource
|
||
|
|
|
||
|
|
[OpenTelemetry resource semantic conventions] include many attribute definitions that are defined as experimental.
|
||
|
|
To have experimental semantic conventions be added by [resource detectors] set the `OTEL_GO_X_RESOURCE` environment variable.
|
||
|
|
The value set must be the case-insensitive string of `"true"` to enable the feature.
|
||
|
|
All other values are ignored.
|
||
|
|
|
||
|
|
<!-- TODO: document what attributes are added by which detector -->

#### Examples
|
||
|
|
|
||
|
|
Enable experimental resource semantic conventions.
|
||
|
|
|
||
|
|
```console
|
||
|
|
export OTEL_GO_X_RESOURCE=true
|
||
|
|
```
|
||
|
|
|
||
|
|
Disable experimental resource semantic conventions.
|
||
|
|
|
||
|
|
```console
|
||
|
|
unset OTEL_GO_X_RESOURCE
|
||
|
|
```
|
||
|
|
|
||
|
|
## Compatibility and Stability
|
||
|
|
|
||
|
|
Experimental features do not fall within the scope of the OpenTelemetry Go versioning and stability [policy](../../../VERSIONING.md).
|
||
|
|
These features may be removed or modified in successive version releases, including patch versions.
|
||
|
|
|
||
|
|
When an experimental feature is promoted to a stable feature, a migration path will be included in the changelog entry of the release.
|
||
|
|
There is no guarantee that any environment variable feature flags that enabled the experimental feature will be supported by the stable version.
|
||
|
|
If they are supported, they may be accompanied with a deprecation notice stating a timeline for the removal of that support.
