exphist: replace min, max, sum, and count with atomics (#8025)
This is the first PR towards a lockless fast-path for the exponential histogram aggregation. It just replaces use of min, max, sum and counts with atomic types. You can see the full set of planned changes in https://github.com/open-telemetry/opentelemetry-go/compare/main...dashpole:opentelemetry-go:lockless_exphist_ai. The implementation is largely based on https://github.com/open-telemetry/opentelemetry-go/pull/7535 (which I implemented by hand), but with help from an AI to break it down into smaller PRs, and simplify aspects of the design.

Add tests for exponential histogram concurrent-safety edge-cases (#8024)
Part of https://github.com/open-telemetry/opentelemetry-go/issues/7796 Improve test coverage of the concurrent-safety of exponential histogram aggregations. This adds two tests: * ZeroValues, which checks that the handling of zero values is correct in concurrent scenarios * RescalingStress, which generates inputs that intentionally cause lots of concurrent rescales. The RescalingStress test inputs the same values into a serial version and parallel version of the exponential histogram aggregation and verifies that the output buckets match afterwards. I used AI to identify where we were missing coverage, and to design and help implement the tests. I've reviewed and modified the tests as needed. |

Improve aggregation concurrent safe tests (#8021)
I'm taking a stab at improving the ConcurrentSafe tests for aggregations before taking on the lockless exponential histogram implementation again. Part of https://github.com/open-telemetry/opentelemetry-go/issues/7796 This PR includes a few improvements: * All concurrent-safe tests now use 10 different attribute sets to make sure we are testing concurrent increments that result in an overflow (the cardinality limit of the test is 3). * All concurrent-safe tests for floats now include decimal valued-inputs. * Improved the validation of the collected metrics: * Validate the total after multiple collects. * Validate that increments are made to the correct bucket for histograms * Validate that the overflow attribute set has the correct total value. This uncovered an apparent race condition where the lastvalue aggregation can collect a value of zero even when no zero-value is recorded. I added a TODO, and will fix this in a follow-up. I used AI to help me design and implement tests, but requested each of the changes, and reviewed the output. --------- Co-authored-by: Tyler Yahn <MrAlias@users.noreply.github.com> |

Add benchmarks for end-to-end metrics SDK usage (#7768)
### Objective Part of https://github.com/open-telemetry/opentelemetry-go/issues/7743. I need a benchmark that can demonstrate the performance of using our API, SDK, and attributes packages together when following our performance guide. https://github.com/open-telemetry/opentelemetry-go/blob/main/CONTRIBUTING.md#attribute-and-option-allocation-management. I settled on benchmarking three scenarios: "Precomputed", "Dynamic", and "Naive". In the "Precomputed" scenario, it is assumed that the attribute set being measured against is known ahead of time, and that the instrumentation author can enumerate all possible sets, and precompute whatever they want, and keep references to it. In the "Dynamic" scenario, it is assumed that the attribute set being measured against is not known ahead of time, and that it is not feasible to enumerate all possible attribute sets ahead of time. However, this scenario still assumes bounded cardinality, as writing metrics with an unbounded cardinality is not the intended use of the API. I had originally written these benchmarks with varying overall cardinality, but the cardinality does not impact the test results, as long as it is reasonable and bounded (e.g. < 100,000). In the "Naive" scenario, it is assumed the user uses the API in the simplest, most ergonomic way. This is an attempt to measure the "default" experience of our API + SDK that users get when they use it. I also found that relative benchmark results did not change when different levels of parallelism are used, so all benchmark results are single-threaded. ### Results ``` goos: linux goarch: amd64 pkg:

(Dynamic), WithAttributes is worse than WithAttributeSet (mostly 1 extra allocation). * When an attribute filter is applied, the performance of the SDK degrades significantly. In the Precomputed case with 10 attributes, the performance goes from 50ns to 1000ns, and from 0 allocations to 2 allocations. |

linting: add depguard rule to enforce semconv version (#8041)
### Description This PR adds a `depguard` linter rule to [.golangci.yml](file:///Users/ijasahammed/Documents/open_source/opentelemetry-go/.golangci.yml) to enforce the use of the latest semantic convention version (`v1.40.0`). This rule ensures that: - Any new code importing `otel/semconv` must use `v1.40.0`. - The `semconv/` directory itself is excluded from this check to avoid linting legacy definitions. - The `zipkin exporter` is excluded from this check - Updated `semconv` version to v1.40.0 in the `sdk/log/logger_bench_test.go` test. ### Verification Results I verified this change locally using the following steps: 1. **Full Linter Run**: Ran `make precommit` (which executes `golangci-lint run`). It passed with **0 issues** across the entire repository. 2. **Smoke Test**: Added a temporary import of `go.opentelemetry.io/otel/semconv/v1.20.0` in trace.go. The linter correctly reported the violation: > `trace.go:7:2: import 'go.opentelemetry.io/otel/semconv/v1.20.0' is not allowed from list 'semconv': Use go.opentelemetry.io/otel/semconv/v1.40.0 instead. (depguard)` This change is not performance-critical and does not affect the library's runtime behavior. ### Checklist - [x] Signed CLA - [x] `make precommit` passes. - [x] CHANGELOG.md updated. (Not required) Fixes #7842 --------- Co-authored-by: Robert Pająk <pellared@hotmail.com> Co-authored-by: Damien Mathieu <42@dmathieu.com> |

Release v1.42.0/v0.64.0/v0.18.0/v0.0.16 (#8006)
### Added - Add `go.opentelemetry.io/otel/semconv/v1.40.0` package. The package contains semantic conventions from the `v1.40.0` version of the OpenTelemetry Semantic Conventions. See the [migration documentation](./semconv/v1.40.0/MIGRATION.md) for information on how to upgrade from `go.opentelemetry.io/otel/semconv/v1.39.0`. (#7985) - Add `Err` and `SetErr` on `Record` in `go.opentelemetry.io/otel/log` to attach an error and set record exception attributes in `go.opentelemetry.io/otel/log/sdk`. (#7924) ### Changed - `TracerProvider.ForceFlush` in `go.opentelemetry.io/otel/sdk/trace` joins errors together and continues iteration through SpanProcessors as opposed to returning the first encountered error without attempting exports on subsequent SpanProcessors. (#7856) ### Fixed - Fix missing `request.GetBody` in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp` to correctly handle HTTP2 GOAWAY frame. (#7931) - Fix semconv v1.39.0 generated metric helpers skipping required attributes when extra attributes were empty. (#7964) - Preserve W3C TraceFlags bitmask (including the random Trace ID flag) during trace context extraction and injection in `go.opentelemetry.io/otel/propagation`. (#7834) ### Removed - Drop support for [Go 1.24]. (#7984) |

TracerProvider ForceFlush() Error Fix (#7856)
Previously upon a SpanProcessor's ForceFlush returning an error, it would return that error and not attempt to flush subsequent SpanProcessors. Now when an error is encountered, it will Join the new error with the existing errors and continue iterating through the SpanProcessors and return the consolidated error at the end of iteration. This is in line with the workflow found in LoggerProvider's ForceFlush. --------- Co-authored-by: Robert Pająk <pellared@hotmail.com> |

Release 1.41.0/0.63.0/0.17.0/0.0.15 (#7977)
This release is the last to support [Go 1.24]. The next release will require at least [Go 1.25]. ### Added - Support testing of [Go 1.26]. (#7902) ### Fixed - Update `Baggage` in `go.opentelemetry.io/otel/propagation` and `Parse` and `New` in `go.opentelemetry.io/otel/baggage` to comply with W3C Baggage specification limits. `New` and `Parse` now return partial baggage along with an error when limits are exceeded. Errors from baggage extraction are reported to the global error handler. (#7880) [Go 1.26]: https://go.dev/doc/go1.26 [Go 1.25]: https://go.dev/doc/go1.25 [Go 1.24]: https://go.dev/doc/go1.24 |

sdk/log/observ: guard LogProcessed with Enabled (#7848)
Guards SLP.LogProcessed with processed.Enabled(ctx) to avoid building metric options/attributes when the processed counter is disabled. BenchmarkSLP (noop MeterProvider): LogProcessedWithError: ~106 ns/op, 232 B/op, 3 allocs/op -> ~0.46 ns/op, 0 B/op, 0 allocs/op No behavior change when enabled; existing tests cover enabled path. I don't believe this is a "notable" change, so doesn't need a CHANGELOG entry.

Release v1.40.0 (#7859)
### Added - Add `Enabled` method to all synchronous instrument interfaces (`Float64Counter`, `Float64UpDownCounter`, `Float64Histogram`, `Float64Gauge`, `Int64Counter`, `Int64UpDownCounter`, `Int64Histogram`, `Int64Gauge`,) in `go.opentelemetry.io/otel/metric`. This stabilizes the synchronous instrument enabled feature, allowing users to check if an instrument will process measurements before performing computationally expensive operations. (#7763) - Add `AlwaysRecord` sampler in `go.opentelemetry.io/otel/sdk/trace`. (#7724) - Add `go.opentelemetry.io/otel/semconv/v1.39.0` package. The package contains semantic conventions from the `v1.39.0` version of the OpenTelemetry Semantic Conventions. See the [migration documentation](https://github.com/open-telemetry/opentelemetry-go/blob/298cbedf256b7a9ab3c21e41fc5e3e6d6e4e94aa/semconv/v1.39.0/MIGRATION.md) for information on how to upgrade from `go.opentelemetry.io/otel/semconv/v1.38.0.` (#7783, #7789) ### Changed - `Exporter` in `go.opentelemetry.io/otel/exporter/prometheus` ignores metrics with the scope `go.opentelemetry.io/contrib/bridges/prometheus`. This prevents scrape failures when the Prometheus exporter is misconfigured to get data from the Prometheus bridge. (#7688) - Improve performance of concurrent histogram measurements in `go.opentelemetry.io/otel/sdk/metric`. (#7474) - Add experimental observability metrics in `go.opentelemetry.io/otel/exporters/stdout/stdoutmetric`. (#7492) - Improve the concurrent performance of `HistogramReservoir` in `go.opentelemetry.io/otel/sdk/metric/exemplar` by 4x. (#7443) - Improve performance of concurrent synchronous gauge measurements in `go.opentelemetry.io/otel/sdk/metric`. (#7478) - Improve performance of concurrent exponential histogram measurements in `go.opentelemetry.io/otel/sdk/metric`. (#7702) - Improve the concurrent performance of `FixedSizeReservoir` in `go.opentelemetry.io/otel/sdk/metric/exemplar`. (#7447) - The `rpc.grpc.status_code` attribute in the experimental metrics emitted from `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc` is replaced with the `rpc.response.status_code` attribute to align with the semantic conventions. (#7854) - The `rpc.grpc.status_code` attribute in the experimental metrics emitted from `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc` is replaced with the `rpc.response.status_code` attribute to align with the semantic conventions. (#7854) ### Fixed - Fix bad log message when key-value pairs are dropped because of key duplication in `go.opentelemetry.io/otel/sdk/log`. (#7662) - Fix `DroppedAttributes` on `Record` in `go.opentelemetry.io/otel/sdk/log` to not count the non-attribute key-value pairs dropped because of key duplication. (#7662) - Fix `SetAttributes` on `Record` in `go.opentelemetry.io/otel/sdk/log` to not log that attributes are dropped when they are actually not dropped. (#7662) - `WithHostID` detector in `go.opentelemetry.io/otel/sdk/resource` to use full path for `ioreg` command on Darwin (macOS). (#7818) - Fix missing `request.GetBody` in `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp` to correctly handle HTTP2 GOAWAY frame. (#7794) ### Deprecated - Deprecate `go.opentelemetry.io/otel/exporters/zipkin`. For more information, see the [OTel blog post deprecating the Zipkin exporter](https://opentelemetry.io/blog/2025/deprecating-zipkin-exporters/).

refactor: modernize code (#7850)
Enable the [`modernize`](https://golangci-lint.run/docs/linters/configuration/#modernize) linter in the golangci-lint configuration and fix the reported issues by running `golangci-lint run --enable-only modernize --fix`. The `modernize` linter is internally the same as [gopls modernize](https://pkg.go.dev/golang.org/x/tools/go/analysis/passes/modernize). Similar to #7089. |

Optimize fixedsize reservoir (#7447)
~Depends on #7441, #7443~ This improves the concurrent performance of the fixed size reservoir's Offer function by 4x (i.e. 75% reduction). This improves the performance of Measure() for fixed-size reservoirs by 60% overall. Accomplish this by: * using a single atomic for count and next. This assumes that both can fit in a uint32. * only use a lock to guard changing `w` and `next` together.

resource: specify full path for ioreg command in Darwin host ID reader (#7818)
Use full path when calling `ioreg` to mitigate potential malicious code execution in case of [Path Interception](https://attack.mitre.org/techniques/T1574/007/). Note that path interception typically requires the attacker to influence the environment or place a malicious executable earlier in $PATH, which, in this context, generally implies the script itself would need to be introduced/uploaded (or otherwise placed/executed) in the target environment for the attacker’s substitute `ioreg` to be reached during execution.

Optimize histogram reservoir (#7443)
This improves the concurrent performance of the histogram reservoir's
Offer function by 4x (i.e. 75% reduction).
Accomplish this by locking each measurement, rather than locking around
the entire storage. Also, defer extracting the trace context from
context.Context until collection time. This improves the performance of
Offer, which is on the measure hot path. Exemplars are often
overwritten, so deferring the operation until Collect reduces the
overall work.
```
│ main.txt │ hist.txt │
│ sec/op │ sec/op vs base │
FixedSizeReservoirOffer-24 211.4n ± 3% 177.5n ± 3% -16.04% (p=0.002 n=6)
HistogramReservoirOffer-24 200.85n ± 2% 47.41n ± 2% -76.40% (p=0.002 n=6)
geomean 206.1n 91.73n -55.48%
```
Benchmarks for Measure:
```
│ main.txt │ histres.txt │
│ sec/op │ sec/op vs base │
SyncMeasure/NoView/ExemplarsEnabled/Int64Histogram/Attributes/0-24 436.7n ± 4% 114.8n ± 5% -73.72% (p=0.002 n=6)
SyncMeasure/NoView/ExemplarsEnabled/Int64Histogram/Attributes/10-24 472.2n ± 2% 169.7n ± 8% -64.08% (p=0.002 n=6)

```
I explored using a []atomic.Pointer[measurement], but this had similar
performance while being much more complex (needing a sync.Pool to
eliminate allocations). The single-threaded performance was also much
worse for that solution. See
https://github.com/open-telemetry/opentelemetry-go/compare/main...dashpole:optimize_histogram_reservoir_old.

Use sync.Map and atomics for fixed bucket histograms (#7474)
Implement a lockless histogram using atomics, and use a sync.Map for attribute access. This improves performance by ~2x. The design is very similar to https://github.com/open-telemetry/opentelemetry-go/pull/7427, but with one additional change to make the histogram data point itself atomic: * For cumulative histograms, which do not use a hot/cold limitedSyncMap, we use a hot/cold data point.

Release v1.39.0 (#7676)
## Overview ### Added - Greatly reduce the cost of recording metrics in `go.opentelemetry.io/otel/sdk/metric` using hashing for map keys. (#7175) - Add `WithInstrumentationAttributeSet` option to `go.opentelemetry.io/otel/log`, `go.opentelemetry.io/otel/metric`, and `go.opentelemetry.io/otel/trace` packages. This provides a concurrent-safe and performant alternative to `WithInstrumentationAttributes` by accepting a pre-constructed `attribute.Set`. (#7287) - Add experimental observability for the Prometheus exporter in `go.opentelemetry.io/otel/exporters/prometheus`. Check the `go.opentelemetry.io/otel/exporters/prometheus/internal/x` package documentation for more information. (#7345) - Add experimental observability metrics in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. (#7353) - Add temporality selector functions `DeltaTemporalitySelector`, `CumulativeTemporalitySelector`, `LowMemoryTemporalitySelector` to `go.opentelemetry.io/otel/sdk/metric`. (#7434) - Add experimental observability metrics for simple log processor in `go.opentelemetry.io/otel/sdk/log`. (#7548) - Add experimental observability metrics in `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`. (#7459) - Add experimental observability metrics in `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`. (#7486) - Add experimental observability metrics for simple span processor in `go.opentelemetry.io/otel/sdk/trace`. (#7374) - Add experimental observability metrics in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#7512) - Add experimental observability metrics for manual reader in `go.opentelemetry.io/otel/sdk/metric`. (#7524) - Add experimental observability metrics for periodic reader in `go.opentelemetry.io/otel/sdk/metric`. (#7571) - Support `OTEL_EXPORTER_OTLP_LOGS_INSECURE` and `OTEL_EXPORTER_OTLP_INSECURE` environmental variables in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#7608) - Add `Enabled` method to the `Processor` interface in `go.opentelemetry.io/otel/sdk/log`. All `Processor` implementations now include an `Enabled` method. (#7639) - The `go.opentelemetry.io/otel/semconv/v1.38.0` package. The package contains semantic conventions from the `v1.38.0` version of the OpenTelemetry Semantic Conventions. See the [migration documentation](./semconv/v1.38.0/MIGRATION.md) for information on how to upgrade from `go.opentelemetry.io/otel/semconv/v1.37.0.`(#7648) ### Changed - `Distinct` in `go.opentelemetry.io/otel/attribute` is no longer guaranteed to uniquely identify an attribute set. Collisions between `Distinct` values for different Sets are possible with extremely high cardinality (billions of series per instrument), but are highly unlikely. (#7175) - `WithInstrumentationAttributes` in `go.opentelemetry.io/otel/trace` synchronously de-duplicates the passed attributes instead of delegating it to the returned `TracerOption`. (#7266) - `WithInstrumentationAttributes` in `go.opentelemetry.io/otel/meter` synchronously de-duplicates the passed attributes instead of delegating it to the returned `MeterOption`. (#7266) - `WithInstrumentationAttributes` in `go.opentelemetry.io/otel/log` synchronously de-duplicates the passed attributes instead of delegating it to the returned `LoggerOption`. (#7266) - Rename the `OTEL_GO_X_SELF_OBSERVABILITY` environment variable to `OTEL_GO_X_OBSERVABILITY` in `go.opentelemetry.io/otel/sdk/trace`, `go.opentelemetry.io/otel/sdk/log`, and `go.opentelemetry.io/otel/exporters/stdout/stdouttrace`. (#7302) - Improve performance of histogram `Record` in `go.opentelemetry.io/otel/sdk/metric` when min and max are disabled using `NoMinMax`. (#7306) - Improve error handling for dropped data during translation by using `prometheus.NewInvalidMetric` in `go.opentelemetry.io/otel/exporters/prometheus`. ⚠️ **Breaking Change:** Previously, these cases were only logged and scrapes succeeded. Now, when translation would drop data (e.g., invalid label/value), the exporter emits a `NewInvalidMetric`, and Prometheus scrapes **fail with HTTP 500** by default. To preserve the prior behavior (scrapes succeed while errors are logged), configure your Prometheus HTTP handler with: `promhttp.HandlerOpts{ ErrorHandling: promhttp.ContinueOnError }`. (#7363) - Replace fnv hash with xxhash in `go.opentelemetry.io/otel/attribute` for better performance. (#7371) - The default `TranslationStrategy` in `go.opentelemetry.io/exporters/prometheus` is changed from `otlptranslator.NoUTF8EscapingWithSuffixes` to `otlptranslator.UnderscoreEscapingWithSuffixes`. (#7421) - Improve performance of concurrent measurements in `go.opentelemetry.io/otel/sdk/metric`. (#7427) - Include W3C TraceFlags (bits 0–7) in the OTLP `Span.Flags` field in `go.opentelemetry.io/exporters/otlp/otlptrace/otlptracehttp` and `go.opentelemetry.io/exporters/otlp/otlptrace/otlptracegrpc`. (#7438) - The `ErrorType` function in `go.opentelemetry.io/otel/semconv/v1.37.0` now handles custom error types. If an error implements an `ErrorType() string` method, the return value of that method will be used as the error type. (#7442) ### Fixed - Fix `WithInstrumentationAttributes` options in `go.opentelemetry.io/otel/trace`, `go.opentelemetry.io/otel/metric`, and `go.opentelemetry.io/otel/log` to properly merge attributes when passed multiple times instead of replacing them. Attributes with duplicate keys will use the last value passed. (#7300) - The equality of `attribute.Set` when using the `Equal` method is not affected by the user overriding the empty set pointed to by `attribute.EmptySet` in `go.opentelemetry.io/otel/attribute`. (#7357) - Return partial OTLP export errors to the caller in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. (#7372) - Return partial OTLP export errors to the caller in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#7372) - Return partial OTLP export errors to the caller in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`. (#7372) - Return partial OTLP export errors to the caller in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`. (#7372) - Return partial OTLP export errors to the caller in `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`. (#7372) - Return partial OTLP export errors to the caller in `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`. (#7372) - Fix `AddAttributes`, `SetAttributes`, `SetBody` on `Record` in `go.opentelemetry.io/otel/sdk/log` to not mutate input. (#7403) - Do not double record measurements of `RecordSet` methods in `go.opentelemetry.io/otel/semconv/v1.37.0`. (#7655) - Do not double record measurements of `RecordSet` methods in `go.opentelemetry.io/otel/semconv/v1.36.0`. (#7656) ### Removed - Drop support for [Go 1.23]. (#7274) - Remove the `FilterProcessor` interface in `go.opentelemetry.io/otel/sdk/log`. The `Enabled` method has been added to the `Processor` interface instead. All `Processor` implementations must now implement the `Enabled` method. Custom processors that do not filter records can implement `Enabled` to return `true`. (#7639) |

sdk/log: move Enabled method from FilterProcessor to Processor (#7639)
Fixes #7617 Simplify the Logs SDK by unifying processor capabilities into a single interface. - Add `Enabled(ctx context.Context, p EnabledParameters) bool` to `sdk/log.Processor`. - Remove `sdk/log.FilterProcessor` interface. `Processor` implementations must now implement the `Enabled` method. Custom processors that do not filter records can implement `Enabled` to return `true`. |

Replace fnv with xxhash (#7497)
**Objective**: - Performance comparison between fnv and xxhash in terms of ops/sec, allocations and collisions - Implement xxhash according to first objective **Changes**: - fnv is replaced by xxhash. Perform stats: - **Collision**: No collision upto 100M - **Allocations**: Same in both cases - **Ops/sec**: xxhash performed better in cases with medium to large strings **Benchmarks**: ``` benchstat old.txt new.txt goos: darwin goarch: arm64 pkg: go.opentelemetry.io/otel/attribute cpu: Apple M2 │ old.txt │ new.txt │ │ sec/op │ sec/op vs base │ NewSet-8 205.5n ± 1% 229.4n ± 1% +11.61% (p=0.002 n=6) NewSetSmallStrings-8 160.5n ± 1% 169.0n ± 5% +5.26% (p=0.002 n=6) NewSetMediumStrings-8 263.8n ± 6% 185.0n ± 1% -29.89% (p=0.002 n=6) NewSetLargeStrings-8 426.4n ± 9% 210.2n ± 1% -50.72% (p=0.002 n=6) NewSetVeryLargeStrings-8 1012.5n ± 7% 238.7n ± 2% -76.43% (p=0.002 n=6) NewSetHugeStrings-8 3622.0n ± 8% 397.1n ± 1% -89.04% (p=0.002 n=6) geomean 488.6n 228.6n -53.21% │ old.txt │ new.txt │ │ B/op │ B/op vs base │ NewSet-8 448.0 ± 0% 448.0 ± 0% ~ (p=1.000 n=6) ¹ NewSetSmallStrings-8 320.0 ± 0% 320.0 ± 0% ~ (p=1.000 n=6) ¹ NewSetMediumStrings-8 320.0 ± 0% 320.0 ± 0% ~ (p=1.000 n=6) ¹ NewSetLargeStrings-8 320.0 ± 0% 320.0 ± 0% ~ (p=1.000 n=6) ¹ NewSetVeryLargeStrings-8 320.0 ± 0% 320.0 ± 0% ~ (p=1.000 n=6) ¹ NewSetHugeStrings-8 320.0 ± 0% 320.0 ± 0% ~ (p=1.000 n=6) ¹ geomean 338.5 338.5 +0.00% ¹ all samples are equal │ old.txt │ new.txt │ │ allocs/op │ allocs/op vs base │ NewSet-8 1.000 ± 0% 1.000 ± 0% ~ (p=1.000 n=6) ¹ NewSetSmallStrings-8 1.000 ± 0% 1.000 ± 0% ~ (p=1.000 n=6) ¹ NewSetMediumStrings-8 1.000 ± 0% 1.000 ± 0% ~ (p=1.000 n=6) ¹ NewSetLargeStrings-8 1.000 ± 0% 1.000 ± 0% ~ (p=1.000 n=6) ¹ NewSetVeryLargeStrings-8 1.000 ± 0% 1.000 ± 0% ~ (p=1.000 n=6) ¹ NewSetHugeStrings-8 1.000 ± 0% 1.000 ± 0% ~ (p=1.000 n=6) ¹ geomean 1.000 1.000 +0.00% ¹ all samples are equal ``` Previous implementation for reference: https://github.com/open-telemetry/opentelemetry-go/blame/d0483a7c89d936dcced557fb523465daeac16967/CHANGELOG.md#L16 --------- Co-authored-by: Robert Pająk <pellared@hotmail.com> |
