[Serverless] Bump Datadog.Serverless.Compat to 1.5.0 by Lewis-E · Pull Request #8602 · DataDog/dd-trace-dotnet

Lewis-E · 2026-05-11T17:17:09Z

Summary

Bumps the Datadog.Serverless.Compat PackageReference in tracer/src/Datadog.AzureFunctions/Datadog.AzureFunctions.csproj from 1.4.0 → 1.5.0.
1.5.0 ships multifunction named-pipe coordination for .NET on Azure Functions Premium plans. It bundles the datadog-serverless-compat/v0.24.0 binary, which contains the dual TCP+pipe listener (serverless-components#94) and best-effort TCP-8126 bind (serverless-components#129) — both required to land the named-pipe path merged in #8164.

Test plan

CI green (csproj-only change; should be a no-op outside of Datadog.AzureFunctions packaging)
Confirm a built Datadog.AzureFunctions package resolves Datadog.Serverless.Compat 1.5.0 from NuGet at restore time

Comparing candidate commit 49cee6b in PR branch lewis/SVLS-8244/update-compat-version with baseline commit 0f0a34a in branch master.

Some scenarios are present only in baseline or only in candidate runs. If you didn't create or remove some scenarios in your branch, this maybe a sign of crashed benchmarks 💥💥💥

Found 4 performance improvements and 1 performance regressions! Performance is the same for 51 metrics, 16 unstable metrics, 90 known flaky benchmarks, 36 flaky benchmarks without significant changes.

Explanation

This is an A/B test comparing a candidate commit's performance against that of a baseline commit. Performance changes are noted in the tables below as:

🟩 = significantly better candidate vs. baseline
🟥 = significantly worse candidate vs. baseline

We compute a confidence interval (CI) over the relative difference of means between metrics from the candidate and baseline commits, considering the baseline as the reference.

If the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD), the change is considered significant.

Feel free to reach out to #apm-benchmarking-platform on Slack if you have any questions.

More details about the CI and significant changes

You can imagine this CI as a range of values that is likely to contain the true difference of means between the candidate and baseline commits.

CIs of the difference of means are often centered around 0%, because often changes are not that big:

---------------------------------(------|---^--------)-------------------------------->
                              -0.6%    0%  0.3%     +1.2%
                                 |          |        |
         lower bound of the CI --'          |        |
sample mean (center of the CI) -------------'        |
         upper bound of the CI ----------------------'

As described above, a change is considered significant if the CI is entirely outside the configured SIGNIFICANT_IMPACT_THRESHOLD (or the deprecated UNCONFIDENCE_THRESHOLD).

For instance, for an execution time metric, this confidence interval indicates a significantly worse performance:

----------------------------------------|---------|---(---------^---------)---------->
                                       0%        1%  1.3%      2.2%      3.1%
                                                  |   |         |         |
       significant impact threshold --------------'   |         |         |
                      lower bound of CI --------------'         |         |
       sample mean (center of the CI) --------------------------'         |
                      upper bound of CI ----------------------------------'

Comparison explanation

Execution-time benchmarks measure the whole time it takes to execute a program, and are intended to measure the one-off costs. Cases where the execution time results for the PR are worse than latest master results are highlighted in **red**. The following thresholds were used for comparing the execution times:

Welch test with statistical test for significance of 5%
Only results indicating a difference greater than 5% and 5 ms are considered.

Note that these results are based on a single point-in-time result for each branch. For full results, see the dashboard.

Graphs show the p99 interval based on the mean and StdDev of the test run, as well as the mean value of the run (shown as a diamond below the graph).
