Summary of changes

  • Add distributed tracing for Azure Event Grid triggers and output bindings in isolated Azure Functions.
  • Create azure_eventgrid.receive spans linked to producer spans and propagate baggage to function invocations.

Reason for change

Complete Azure Event Grid trace correlation through Azure Functions while preserving producer/consumer causality.

Implementation details

  • Extract W3C context from CloudEvent extension attributes and support single events and batches.
  • Add DD_TRACE_AZURE_EVENTGRID_BATCH_LINKS_ENABLED to control producer span links.
  • Share Azure Functions binding extraction helpers across messaging integrations.

Test coverage

  • Add unit coverage for Event Grid context and baggage extraction.
  • Add emulator-backed integration tests and snapshots for SDK publishing and output bindings.

Other details

Benchmark execution time: 2026-07-29 10:32:29

Comparing candidate commit 27f0125 in PR branch pmartinez/event-grid-functions with baseline commit 4e79e39 in branch master.

📊 Benchmarking dashboard

Found 1 performance improvements and 1 performance regressions! Performance is the same for 70 metrics, 0 unstable metrics, 63 known flaky benchmarks, 63 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).
