feat: Added new statistics interface / removed statistics publisher by jmachowinski · Pull Request #3203 · ros2/rclcpp

jmachowinski · 2026-07-17T16:49:49Z

Description

This removes the half backed statistics implementation and replaces it with a interface that can be implemented by a third party pkg to archive the same functionality.

Is this user-facing behavior change?

Yes, we remove an existing feature. Due to recent bug reports I believe almost nobody was using it.
But as states, this also enables community pkgs to replicate the existing behavior.

Did you use Generative AI?

Yes, SWE-1.7

This reduced the compile time of a node with 1 sub and 1 publisher from 6.32s to 4.91s on a Ryzen 9900X

I am not against this approach, imo old implementation clearly wasn't pulling its weight anyway. a few comments below.

should we not give deprecation period before removal? statistics has been there for a long time, there would be some users who might use the statistics.
no default implementation provided by mainline? i think user can still do enable/disable the statistics feature on the subscription, and then mainline provides the default collector?
this still supports rclcpp-only, so rclpy and other client libraries can't benefit. we know that this is the same limitation the old design had. probably this is next step after this PR, for longer term I think that statistics hooks is an rcl-level event/emission API, which would give all client libraries and all entity types (publishers, services, actions) a shared mechanism, with a default implementation maintained and tested in mainline.

jmachowinski · 2026-09-24T13:58:08Z

Note, we talked about this on roscon, and we came to the conclusion, that we would remove this completely and not even provide an interface for collecting statistics.
The reason for this, is that tooling appeared, that hooks into tracepoints. This seems to to be the better way forward for collecting statistics.

I think that we should probably also make a discourse post about this after we remove it. I don't think anyone will be impacted, but better to be overly-communicative.
