Motivation

Short-lived applications can lose exposures queued while another batch is being sent. Shutdown currently signals the worker without waiting for a final drain, and a concurrent evaluation can enqueue after shutdown begins.

Changes and Decisions

Separate the existing local sender from exposure batching, give the Feature Flags module ownership of its lifetime, and dispose its settings subscriptions. Exposure shutdown rejects new enqueue attempts, drains queued events and waits at most ten seconds for the worker; a stalled network cannot indefinitely block termination.

This is the single-commit middle PR, based on discovery #9352. Both configuration modes keep their historical fixed EVP v2 route, headers and redirect defaults. There is no discovery-based selection or direct-intake activation here; the complete Agentless policy remains in #9235.

Benchmarks

Benchmark execution time: 2026-10-01 23:25:09

Comparing candidate commit 9a8280d in PR branch leo.romanovsky/fflsdk-189-dotnet-exposure-lifecycle with baseline commit 0610b13 in branch master.

📊 Benchmarking dashboard

Found 0 performance improvements and 12 performance regressions! Performance is the same for 60 metrics, 0 unstable metrics, 75 known flaky benchmarks, 49 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 ----------------------------------'
