- Ingest event streams (streaming connectors).
- Apply lightweight filtering and normalization (stream processing).
- Enrich events via a demographic API with caching.
- Batch predictions from a cloud ML service for advanced segments.
- Aggregate metrics and write to a time-series database.
- Emit metrics/logs and trace requests for observability.
- Auto-scale workers based on incoming event rate.
Key techniques used: modular pipelines, scripting for enrichment logic, parallel processing of independent partitions, robust retry for API calls, observability for monitoring, and resource optimization with streaming.
Final Checklist Before Production
- Parameterize and version your pipelines.
- Test scripts and integrations in staging.
- Implement retries, dead-letter handling, and alerting.
- Add structured logging, metrics, and tracing.
- Benchmark and tune concurrency and resource usage.
If you want, I can expand any section into step-by-step instructions with example scripts for XPE Tool’s scripting language — tell me which technique and what runtime (Python/JS) you prefer.
