perf(ci): Skip py3.14 builds for confluent-kafka 2.11.1 and sentry-streams 0.0.39#2359
Merged
Conversation
…reams 0.0.39 Both versions fail on every build for Python 3.14 and are the lone stragglers in their package families (confluent-kafka 2.12.2+ and sentry-streams 0.0.40+ already build on 3.14), so restricting them to <3.14 removes ~8 min of wasted work per build.

confluent-kafka==2.11.1andsentry-streams==0.0.39have no official cp314 wheel on PyPI, so they never produce a 3.14 wheel — and every build wastes time failing to. This restricts both topython_versions = <3.14.Why they never build on 3.14
For 3.11–3.13 the builder downloads prebuilt PyPI wheels (cached, then skipped). For 3.14 it falls back to an sdist build that fails: sentry-streams 0.0.39 uses PyO3 0.24.0 (caps at 3.13, fails in ~1.3 min), and confluent-kafka 2.11.1 spends ~6.5 min compiling librdkafka + deps from source before failing the
librdkafka >= 2.11.1check. The failed wheel never caches, so that work re-runs on every build.Why it's safe
This is version-specific, not a project-wide 3.14 drop: both projects support 3.14 in their next release (confluent-kafka 2.12.2+, sentry-streams 0.0.40+), and those cp314 wheels are already on the internal index. Matches the "skipped older versions" convention in
PYTHON-3.14-UPGRADE.md.Impact
~8 min less per build. Confirmed on this PR's CI — linux amd64 dropped from ~8.7 min to ~0.5 min (arm64 ~7.4→0.6, macOS ~3.0→0.7).
Since the build runs twice (on the PR, and on main) before a deploy, packages should now appear ~16 min sooner end to end.
