Benchmarks

Comparison

Benchmark execution time: 2026-08-31 13:14:41

Comparing candidate commit 79b13e5 in PR branch paullgdc/obfuscation/v04_span with baseline commit 9fb27ea in branch main.

Found 15 performance improvements and 10 performance regressions! Performance is the same for 143 metrics, 10 unstable metrics.

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 ----------------------------------'

It's somewhat unclear how much on parity this approach is with the Trace Agent obfuscation config. We should document this somewhere, and also test the schemas are the same.

I also don't fully understand why we want to keep 2 separate implementations here, one for protobuf, the other for raw spans (using JSON endpoint). These 2 paths look also inconsistent at first glance (pb implementation being more complex and more tested).

I also don't fully understand why we want to keep 2 separate implementations here, one for protobuf, the other for raw spans (using JSON endpoint). These 2 paths look also inconsistent at first glance (pb implementation being more complex and more tested).

The protobuf span struct is obsolete and used only by serverless for their extension. I cannot remove the obfuscate method though as I don't want to break their extension completely.

If we ever want to send protobuf spans to the intake APM clients using libdatadog, we will do it by adding a protobuf serializer to the v1 span struct.
The paths are from what I can tell consistent and I have added tests that run the same cases against both functions.

I'm not too happy that it double obfuscates common operations, which have already been obfuscated once for stats computation.
But that's a future optimization, not a blocker. The implementation looks right to me: trivially obfuscating every span, and avoiding reallocating/copying for stuff which clearly doesn't need to be obfuscated.

ekump

A few things that need fixing, but not blocking. Please create Jira tickets for any follow up work.

I looked only at the libdd-profiling-ffi/Cargo.toml changes, which are fine.

#2472) # Motivation Credit-card obfuscation only checked the single `card.number` tag, but the trace-agent scans all span meta attributes (with an explicit skip-list) # Changes * Replace the single `TAG_CARD_NUMBER` fast-path in `obfuscate_pb_span` and `obfuscate_v04_span` with a full scan of all `span.meta` entries * Skip keys in the built-in skip-list (`should_obfuscate_cc_key`) and the user-configured `keep_values` set Followup for #2418
