The Rust OpenTelemetry implementation
Fixed https://github.com/open-telemetry/opentelemetry-rust/pull/1576 Fix Span kind is always set to "internal".
https://github.com/open-telemetry/opentelemetry-rust/pull/1410 Add experimental synchronous gauge. This is behind the feature flag, and can be enabled by enabling the feature otel_unstable for opentelemetry crate.
https://github.com/open-telemetry/opentelemetry-rust/pull/1410 Guidelines to add new unstable/experimental features.
#1410 Add experimental synchronous gauge
#1471 Configure batch log record processor via OTEL_BLRP_* environment variables and via OtlpLogPipeline::with_batch_config
#1503 Make the documentation for In-Memory exporters visible.
#1526
Performance Improvement : Creating Spans and LogRecords are now faster, by avoiding expensive cloning of Resource for every Span/LogRecord.
Breaking #1313 #1350 Changes how Span links/events are stored to achieve performance gains. See below for details:
Behavior Change: When enforcing max_links_per_span, max_events_per_span
from SpanLimits, links/events are kept in the first-come order. The previous
"eviction" based approach is no longer performed.
Breaking Change Affecting Exporter authors:
SpanData now stores links as SpanLinks instead of EvictedQueue where
SpanLinks is a struct with a Vec of links and dropped_count.
SpanData now stores events as SpanEvents instead of EvictedQueue where
SpanEvents is a struct with a Vec of events and dropped_count.
Breaking Remove TextMapCompositePropagator #1373. Use TextMapCompositePropagator in opentelemetry API.
#1375 Fix metric collections during PeriodicReader shutdown
Breaking #1480 Remove fine grained BatchConfig configurations from BatchLogProcessorBuilder and BatchSpanProcessorBuilder. Use BatchConfigBuilder to construct a BatchConfig instance and pass it using BatchLogProcessorBuilder::with_batch_config or BatchSpanProcessorBuilder::with_batch_config.
Breaking #1480 Remove mutating functions from BatchConfig, use BatchConfigBuilder to construct a BatchConfig instance.
Breaking #1495 Remove Batch LogRecord&Span Processor configuration via non-standard environment variables. Use the following table to migrate from the no longer supported non-standard environment variables to the standard ones.
| No longer supported | Standard equivalent |
|---|---|
| OTEL_BLRP_SCHEDULE_DELAY_MILLIS | OTEL_BLRP_SCHEDULE_DELAY |
| OTEL_BLRP_EXPORT_TIMEOUT_MILLIS | OTEL_BLRP_EXPORT_TIMEOUT |
| OTEL_BSP_SCHEDULE_DELAY_MILLIS | OTEL_BSP_SCHEDULE_DELAY |
| OTEL_BSP_EXPORT_TIMEOUT_MILLIS | OTEL_BSP_EXPORT_TIMEOUT |
Breaking 1455 Make the LoggerProvider Owned
Logger now takes an Owned Logger instead of a Weak<LoggerProviderInner>
LoggerProviderInner is no longer pub (crate)
Logger.provider() now returns &LoggerProvider instead of an Option<LoggerProvider>
1519 Performance improvements
when calling Counter::add() and UpDownCounter::add() with an empty set of attributes
(e.g. counter.Add(5, &[]))
Relase backported bugfixes into v0.21.x:
opentelemetry-prometheus:
opentelemetry-sdk:
This release should been seen as 1.0-rc4 following 1.0-rc3 in v0.20.0. Refer to CHANGELOG.md in individual creates for details on changes made in different creates.
opentelemetry crate now only carries the API types #1186. Use the opentelemetry_sdk crate for the SDK types.trace::noop::NoopSpan no longer implements Default and instead exposes a const DEFAULT value. #1270
SpanBuilder attributes changed from OrderMap<Key, Value> to Vec<KeyValue> and with_attributes_map method is removed from SpanBuilder. This implies that OpenTelemetry API will no longer perform de-dup of attribute Keys. #1293. Please share feedback here, if you are affected.See individual crate changelogs for details.
This release should been seen as 1.0-rc2 following 1.0-rc1 in v0.18.0. Refer to CHANGELOG.md in individual creates for details on changes made in different creates.
