What does this PR do?

Inserts compile-time entity header names directly while retaining validation for dynamic values.

Motivation

Parsing three known header names on every request adds fallible work and linked code without validating user input.

Additional Notes

The optimized WASM artifact drops from 441,261 to 440,912 bytes.

How to test the change?

Run the data-pipeline-core tests and all-feature Clippy.

perf(data-pipeline): avoid parsing static entity header names
7faa90d 
Entity header names are compile-time constants, so parsing them for every request adds code and fallible work without validating dynamic input. Keep value validation and insert the known names directly.

This reduces the optimized WASM artifact from 441,261 to 440,912 bytes with the same Rust and Binaryen toolchain.

Comparison

Benchmark execution time: 2026-09-10 21:01:09

Comparing candidate commit 769d408 in PR branch BridgeAR/2026-09-03-wasm-pipeline-size with baseline commit 8b0fa65 in branch main.

📊 Benchmarking dashboard

Found 2 performance improvements and 0 performance regressions! Performance is the same for 22 metrics, 0 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 ----------------------------------'

# Release proposal for libdd-capabilities-impl, libdd-common,

libdd-profiling-heap-allocator, libdd-remote-config, libdd-sampling,
libdd-shared-runtime, libdd-telemetry, libdd-tinybytes,
libdd-trace-utils and their dependencies

This PR contains version bumps based on public API changes and commits
since last release.


### ⚠️ Crates left out of this proposal affected by its major
bumps

These publishable workspace crates are not part of this release but
their dependency requirement was rewritten on this branch while their
published version still requires the old major. If they are a dependency
on your deployment not including them in the release could result in
duplicate packages or symbol incompatibility.

- `libdd-capabilities` `3.0.1` → `4.0.0` affects: `libdd-crashtracker`,
`libdd-ffe`, `libdd-live-debugger`
- `libdd-capabilities-impl` `5.0.0` → `6.0.0` affects:
`libdd-crashtracker`, `libdd-live-debugger`, `libdd-tracer-flare`
- `libdd-common` `6.0.0` → `7.0.0` affects: `libdd-crashtracker`,
`libdd-ffe`, `libdd-http-client`, `libdd-ipc`, `libdd-live-debugger`,
`libdd-profiling`, `libdd-tracer-flare`
- `libdd-data-pipeline` `10.0.0` → `11.0.0` affects:
`libdd-live-debugger`
- `libdd-remote-config` `5.0.0` → `6.0.0` affects: `libdd-ffe`,
`libdd-live-debugger`, `libdd-tracer-flare`
- `libdd-telemetry` `8.0.0` → `9.0.0` affects: `libdd-crashtracker`
- `libdd-trace-stats` `9.0.0` → `10.0.0` affects: `libdd-ipc`
- `libdd-trace-utils` `12.0.0` → `13.0.0` affects: `libdd-tracer-flare`
