Summary of changes

Guards against future timestamps when extracting pathwayContext and calculating pathwayLatencyNs

Reason for change

We decode the dd-pathway-ctx from inbound headers, and use the decoded PathwayStart to compute pathwayLatencyNs. This is then used to calculate an originTimestamp and is added to _originBuckets. We then only flush _originBuckets for which the start time is <= the current bucket window.

If a "future" timestamp ends up in PathwayStart, then we would end up with that future bucket never being flushed and accumulating. This PR guards against those future timestamps so we don't end up with unbounded growth.

Implementation details

Add two guards:

  • In SetCheckpoint, guard against generating negative pathwayLatencyNs or edgeLatencyNs
  • In PathwayContextEncoder.Decode, reject data points with a "future" PathwayStart time
    • Using a tolerance here of 60s to make sure clock skew issues don't bite us. I think that number seems reasonable, but open to suggestions.
    • I was initially concerned about daylight savings etc, but given we're using UTC for all of this, that shouldn't be an issue

Test coverage

Added a bunch of additional unit tests around this.

yeah idk I'd have used something more loose like 5 minutes, but really this is wet finger engineering

Yeah, exactly, I'm fine with 5 minutes too 🤷‍♂️ I don't know if it's something we have actually observed in practice, so we probably don't have any data to go on either 🤷‍♂️

Benchmarks

Benchmark execution time: 2026-05-21 15:37:36

Comparing candidate commit a8e05f0 in PR branch andrew/data-streams-unbounded-growth with baseline commit ba7828b 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 💥💥💥
Check Gitlab CI job log to find if any benchmark has crashed.

Found 8 performance improvements and 12 performance regressions! Performance is the same for 45 metrics, 7 unstable metrics, 92 known flaky benchmarks, 34 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).
