feat(aot): add DuckType and CallTarget NativeAOT workflows by tonyredondo · Pull Request #8383 · DataDog/dd-trace-dotnet

tonyredondo · 2026-03-27T13:56:06Z

Summary of changes

add a publish-integrated NativeAOT workflow for CallTarget auto-instrumentation
add the generated registry, manifest, rewrite-plan, props, targets, and compatibility artifacts for calltarget-aot
add the runtime CallTarget AOT registration path, contract validation, and single-registry enforcement
add generated adapter support for begin, slow-begin, end, Task/Task<T>, and ValueTask/ValueTask<T> paths
integrate DuckType AOT for constrained instance, argument, return, and async-result bindings
add focused docs and NativeAOT test coverage for the new workflow

Reason for change

CallTarget currently depends on runtime IL emission, which is not compatible with NativeAOT. This branch moves the required adapter generation to build time and wires the generated registry into dotnet publish /p:PublishAot=true so the runtime can execute pre-registered handlers without emitting IL.

Implementation details

keep the existing dynamic IntegrationMapper path for normal JIT runtimes
add the new dd-trace calltarget-aot generate public workflow and the internal rewrite step consumed by generated MSBuild targets
discover InstrumentMethodAttribute definitions directly from Datadog.Trace
match supported target methods, record unsupported shapes with explicit diagnostics, and emit compatibility/reporting artifacts
rewrite the compiled app assembly and selected references so their module initializers root the generated CallTarget registry bootstrap during publish/runtime
add runtime AOT registration, contract validation, and failure behavior in Datadog.Trace
integrate the DuckType AOT companion registry when matched bindings require generated proxies

Test coverage

Verified locally with focused gates:

dotnet build tracer/src/Datadog.Trace.Tools.Runner/Datadog.Trace.Tools.Runner.csproj -c Release --no-restore /m:1 /nodeReuse:false

Other details

This branch is based on master and includes the earlier DuckType NativeAOT work that CallTarget AOT depends on.

Comparing candidate commit 218d0a8 in PR branch feat/calltarget-nativeaot-adapters with baseline commit 017e910 in branch master.

Found 7 performance improvements and 8 performance regressions! Performance is the same for 254 metrics, 19 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 ----------------------------------'

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).
