v0.9.12

Important Notes

WARNING: When updating to v0.9.12 for the first time, latency metrics that aggregate across different versions of baseplate.go may show incorrect results! Dashboards may need to be temporarily filtered to show only specific pods or only a canary deployment to see correct latencies.

Behavior Changes

• Latency Metrics: The latency buckets that are used for prometheus metrics have changed to reflect the baseplate spec.
  • This is likely to cause latency dashboards to incorrectly report high latencies. Filter the dashboard to specific pods or only the canary deployment to verify. This should resolve itself once the deployment is complete.
  • If you were using apdex-style queries with harded-coded le= buckets, these buckets will be changing. Let us know if you need help adjusting your queries to account for this.
• HTTP Size Buckets: The request and response size buckets are changing to reflect the baseplate spec.
  • Again, let us know if you need help accommodating this change.
• Sentry: reporting from trace hooks is now opt-in
• Shutdown: The default shutdown delay is now 5 seconds (up from 1 second) #615

API Changes

• thriftbp: requiredInitialConnections will be retried, rather than returning immediately, to permit more stable startup.
  • Users must opt-in to get this behavior by setting requiredInitialConnections: 1 (or similar) in their configuration.

Compatibility

• Baseplate.go v0.9.12 will require Go 1.19 or later.

Other Highlights

• Added Vault CSI support (set the secrets.json path to be the secrets mount directory)
• Updated and added various Prometheus metrics to match the baseplate spec
• httpbp: Enable passthrough of HTTP ResponseWriter optional interfaces (e.g. to permit hijacking)
