Fixes
General fixes
- Issues: #4522.
A data race happened when emptying buffers of a failing broker, in its thread,
with the statistics callback in main thread gathering the buffer counts.
Solved by resetting the atomic counters instead of initializing them.
Happening since 1.x (#4718). - Issues: #4948
Features BROKER_BALANCED_CONSUMER and SASL_GSSAPI don't depend on
JoinGroup v0 anymore, missing in AK 4.0 and CP 8.0. This PR partially
fixes the linked issue, a complete fix for all features will follow.
Rest of fixes are necessary only for a subsequent Apache Kafka major
version (e.g. AK 5.x).
Happening since 1.x (#5131).
Telemetry fixes
- Issues: #5109
Fix for poll ratio calculation in case the queues are forwarded.
Poll ratio is now calculated per-queue instead of per-instance and
it allows to avoid calculation problems linked to using the same
field.
Happens since 2.6.0 (#5017).
