+      artifacts: true
+  when: on_success
+  tags: ["arch:amd64"]

todo: From @ddyurchenko

Could you please rebase your PR on the latest master and remove allow_failure: true from gating job?
In worst case scenario if we block something that should not be blocked, there is a label mechanism to bypass the gate

Ignore mechanism in bp-runner

Thanks for flagging it! We need to remove allow_failure: true, the bypass mechanism inside bp-runner is specified in https://datadoghq.atlassian.net/wiki/x/LgI1LgE#How-to-bypass%3F.

…efined)

ddyurchenko

Looks good! Both cases where gates should block and where they should let pass work. ✔️

PerfectSlayer

Can you link doc about it?

Gate skippable via performance/ignore-performance-regression label

Is that a GitHub issue label? If so, is it configurable as it does not fit our usual pattern?

bric3 · 2025-06-19T10:25:51Z

@PerfectSlayer The bypass link is mentioned in @ddyurchenko's comment, I added it in the PR description.

Is that a GitHub issue label?

Yes.

If so, is it configurable as it does not fit our usual pattern?

I already brought this to @ddyurchenko, this is something to be addressed in bp-runner PR (which is not merged yet). (Hence the higher threshold at this time).

bric3 · 2025-06-25T13:34:28Z

There are still some concerns about the variability of the benchmarks.

E.g. this PR that sees 9% worse while touching unrelated files.

worse
[+3.367ms; +4.340ms] or [+7.002%; +9.027%]

Cancel GitLab running pipeline on new PR push #9023
Or this PR that see 8% improvement

better
[-379.158µs; -273.744µs] or [-8.414%; -6.075%]

Convert some build file to kotlin dsl #8743

20% was chosen due to variability of the results on unrelated changes. After discussion in lp-sync, 20% won't get us to move forward and entice to fix the problems. So instead choose a closer threshold to 10%.
