Release Notes 0.30

OpenTelemetry Rust 0.30 introduces a few breaking changes to the opentelemetry_sdk crate in the metrics feature. These changes were essential to drive the Metrics SDK towards stability. With this release, the Metrics SDK is officially declared stable. The Metrics API was declared stable last year, and previously, the Logs API, SDK, and OTel-Appender-Tracing were also marked stable. Importantly, no breaking changes have been introduced to components already marked as stable.

It is worth noting that the opentelemetry-otlp crate remains in a Release-Candidate state and is not yet considered stable. With the API and SDK for Logs and Metrics now stable, the focus will shift towards further refining and stabilizing the OTLP Exporters in upcoming releases. Additionally, Distributed Tracing is expected to progress towards stability, addressing key interoperability challenges.

For detailed changelogs of individual crates, please refer to their respective changelog files. This document serves as a summary of the main changes.

Key Changes

Metrics SDK Improvements

1. Stabilized "view" features: Previously under an experimental feature flag, views can now be used to modify the name, unit, description, and cardinality limit of a metric. Advanced view capabilities, such as changing aggregation or dropping attributes, remain under the experimental feature flag.

2. Cardinality capping: Introduced the ability to cap cardinality and configure limits using views.

3. Polished public API: Refined the public API to hide implementation details from exporters, enabling future internal optimizations and ensuring consistency. Some APIs related to authoring custom metric readers have been moved behind experimental feature flags. These advanced use cases require more time to finalize the API surface before being included in the stable release.

Context-Based Suppression

Added the ability to suppress telemetry based on Context. This feature prevents telemetry-induced-telemetry scenarios and addresses a long-standing issue. Note that suppression relies on proper context propagation. Certain libraries used in OTLP Exporters utilize tracing but do not adopt OpenTelemetry's context propagation. As a result, not all telemetry is automatically suppressed with this feature. Improvements in this area are expected in future releases.

⚠️ CI Failure — Incompatible OpenTelemetry Version Bump

Root cause: This PR bumps opentelemetry-otlp from 0.27.0 → 0.31.0, but the other OpenTelemetry crates in the workspace Cargo.toml remain at 0.27:

Crate	Current	Required by otlp 0.31
opentelemetry	0.27	0.31
opentelemetry_sdk	0.27	0.31
tonic	0.12	0.14+

Build error:

error[E0599]: no method named `with_tonic` found for struct `MetricExporterBuilder<NoExporterBuilderSet>`
  --> lnc-metrics/src/otlp.rs:97:10

The MetricExporter::builder().with_tonic() API was removed/changed in opentelemetry-otlp 0.31. This is a breaking API change that requires:

1. Coordinated upgrade of all opentelemetry* crates to 0.31
2. Updating tonic from 0.12 to 0.14+
3. Code changes in lnc-metrics/src/otlp.rs to use the new builder API (.with_tonic() → new pattern)
4. PeriodicReader::builder() API also changed in SDK 0.31 (runtime parameter removed)

Recommendation: This cannot be auto-merged. A manual coordinated upgrade of the full OpenTelemetry stack is needed.

⚠️ CI Failure — Breaking API Change in opentelemetry-otlp 0.31.0

Root cause: opentelemetry_otlp::MetricExporter::builder().with_tonic() no longer exists in v0.31.0.

error[E0599]: no method named `with_tonic` found for struct `MetricExporterBuilder<NoExporterBuilderSet>`
  --> lnc-metrics/src/otlp.rs:97:10

Analysis

This PR bumps opentelemetry-otlp from 0.27.0 to 0.31.0 — spanning 4 breaking releases (0.28, 0.29, 0.30, 0.31). Key breaking changes include:

1. Builder API overhaul — MetricExporter::builder().with_tonic() was removed. In 0.31.0, the tonic transport is configured differently (likely via feature flags and a simplified builder without the with_tonic() step).
2. PeriodicReader API change — PeriodicReader::builder(exporter, runtime::Tokio) likely changed; the runtime parameter was removed in favor of the SDK managing its own async runtime.
3. WithExportConfig trait changes — .with_endpoint() and .with_timeout() may have moved to different builder stages.

Affected file

• lnc-metrics/src/otlp.rs — init_otlp_metrics() function (lines 78-122)

Recommendation

This is a major version migration that requires updating the OTLP exporter initialization code to match the new 0.31.0 API. Suggest reviewing:

• opentelemetry-rust migration guide for 0.28
• Release notes for 0.30
• The 0.31.0 examples in the opentelemetry-rust repo
