Changelog

vNext

v0.22.1

Fixed

  • #1576 Fix Span kind is always set to "internal".

v0.22.0

Deprecated

  • XrayIdGenerator in the opentelemetry-sdk has been deprecated and moved to version 0.10.0 of the opentelemetry-aws crate.

Added

  • #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.

Changed

  • 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, &[]))

  • Breaking Renamed MeterProvider and Meter to SdkMeterProvider and SdkMeter respectively to avoid name collision with public API types. #1328

Fixed

  • #1481 Fix error message caused by race condition when using PeriodicReader

v0.21.2

Fixed

  • Fix delta aggregation metric reuse. #1434
  • Fix max_scale validation of exponential histogram configuration. #1452

v0.21.1

Fixed

  • Fix metric export corruption if gauges have not received a last value. #1363
  • Return consistent Meter for a given scope from MeterProvider. #1351

v0.21.0

Added

  • Log warning if two instruments have the same name with different #1266 casing
  • Log warning if view is created with empty criteria #1266
  • Add exponential histogram support #1267
  • Add opentelemetry::sdk::logs::config() for parity with opentelemetry::sdk::trace::config() #1197

Changed

  • Bump MSRV to 1.65 #1318

  • Default Resource (the one used when no other Resource is explicitly provided) now includes TelemetryResourceDetector, populating "telemetry.sdk.*" attributes. #1194.

  • Bump MSRV to 1.64 #1203

  • Add unit/doc tests for MeterProvider #1220

  • Changed dependency from opentelemetry_api to opentelemetry as the latter is now the API crate. #1226

  • Add in memory span exporter #1216

  • Add in memory log exporter #1231

  • Add Sync bound to the SpanExporter and LogExporter traits #1240

  • Move MetricsProducer config to builders to match other config #1266

  • Return error earlier if readers are shut down #1266

  • Add / to valid characters for instrument names #1269

  • Increase instrument name maximum length from 63 to 255 #1269

  • Updated crate documentation and examples. #1256

  • Replace regex with glob #1301

  • Breaking #1293 makes few breaking changes with respect to how Span attributes are stored to achieve performance gains. See below for details:

    Behavior Change:

    SDK will no longer perform de-duplication of Span attribute Keys. Please share feedback here, if you are affected.

    Breaking Change Affecting Exporter authors:

    SpanData now stores attributes as Vec<KeyValue> instead of EvictedHashMap. SpanData now expose dropped_attributes_count as a separate field.

    Breaking Change Affecting Sampler authors:

    should_sample changes attributes from OrderMap<Key, Value> to Vec<KeyValue>.
