Lazy module loading for FaaS cold start reduction

streamline behavioral
1 file changed
  • __init__.py Heavy modules lazy-loaded on first use; cold-start import count drops from 34 to 16
  • Heavy optional modules (OTel exporters, memray, resilience) deferred to first-use lazy loading. Cold-start module count drops from 34 to 16, significantly reducing FaaS (Lambda/Cloud Run) initialization time. streamline behavioral

TypeScript config wired into runtime behavior

instantiate behavioral
4 files changed
  • schema.ts Full TelemetryConfig env vars: metricsEnabled, logIncludeCaller, logModuleLevels, PII label alignment
  • sampling.ts Config-driven sampling policies wired at runtime
  • pii.ts Custom PII rules wired into write hook via config; hardening profile refactored
  • otel.ts OTLP log export added; metricsEnabled toggle and runtime metric exemplar attachment
  • Remaining TypeScript TelemetryConfig fields wired into runtime: metricsEnabled toggle enables/disables metric collection, logIncludeCaller and logModuleLevels added to schema, custom PII rules wired into the write hook, metric exemplars attached from active OTel trace context. OTLP log export added for Python parity. instantiate behavioral

TypeScript metric wrappers and SLO tracking

instantiate behavioral
3 files changed
  • slo.ts SLO tracking with .value/.count/.total accessors on instruments
  • tracing.ts Tracing wrappers and propagation helpers
  • resilience.ts Resilience primitives (circuit breaker, retry) TypeScript parity
  • TypeScript metric wrappers added with .value/.count/.total accessors on instrument objects for ergonomic metric reading in tests. SLO tracking module added. Resilience primitives (circuit breaker, retry) brought to Python parity. Propagation helpers added. instantiate behavioral

Performance and stress test suites (Python + TypeScript)

qualify internal
3 files changed
  • slo.test.ts SLO and performance tests
  • resilience.test.ts Resilience stress tests
  • tracing.test.ts Tracing performance tests
  • Performance and stress test suites added for both Python and TypeScript. TypeScript tests cover SLO accuracy under load, resilience under saturation, and tracing throughput. Python stress tests verify emission throughput and circuit breaker behavior under load. qualify internal

Kill all surviving Python and TypeScript mutants

qualify internal
2 files changed
  • stryker.config.mjs Stryker config tuned; all TypeScript mutants killed
  • core.py Python mutation survivors killed; pragma no mutate narrowed to module-level init only
  • All remaining Python and TypeScript mutation survivors killed. TypeScript reaches 100% Stryker mutation score. Python mutmut pragma narrowed to module-level init registration (untestable by design). CI mutation gate enforced for both languages. qualify internal
