Everything we used tarpc for was dispatching ... and not much else.

But it also imposed some constraints on the messaging stream, like it did not directly allow us to backpressure directly on the read stream.

Finally, the old code, under some, not understood circumstances, would have file descriptors pile up in the sink, which were not ending up being associated with a message. (I suspect, when a message was dropped on the sender side?!)

This proposes a radically different approach based on message passing instead of streaming:

  • SOCK_SEQSTREAM is used on Linux.
    • Macos does not support this, so we fall back to a dgram socketpair, which results in the same thing, effectively.
  • Windows uses Named Pipe Messages.

The messaging approach promises to strongly tie file descriptors to the passed text, structurally eliminating the possibility of file descriptions leaking.

It also avoids a manual length delimiting codec and stream buffering. It generally avoids all buffering, except the send and receive buffers. In fact, previously we had multiple additional buffering channels around the different executors - and still, in the end we execute stuff serially...

Avoiding tarpc also allows us to trivially tie some metadata directly to the connection. This can still be improved upon. E.g. session_ids are now fundamentally tied to the connection.

Finally we also improve upon connection state stability when messages are dropped: the SidecarOutbox will buffer state-critical data and resubmit when space becomes available.

Benchmarks

Comparison

Benchmark execution time: 2026-03-20 17:01:36

Comparing candidate commit f952dd9 in PR branch bob/prevent-unprocessed with baseline commit b15cd20 in branch main.

Found 4 performance improvements and 0 performance regressions! Performance is the same for 55 metrics, 2 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 ----------------------------------'
