You need to design a data platform that can ingest, process, store, and query large-scale event streams.
Here are the key components:
- Ingest: streaming events from multiple sources
- Processing: lightweight transformations and enrichment
- Storage: hot and cold stores tuned for different workloads
- Access: query and analytic APIs for downstream systems
- Observability: deep visibility into data quality, latency, and system health
You can build an end-to-end data platform with these components. Emphasize observability from day zero: metrics, traces, logs, and data lineage. Provide pragmatic guidance, example code, and deployment considerations.
Some key takeaways:
- Use a compact, evolvable schema with backward compatibility strategies
- Maintain a central registry with versioned schemas and a compatibility checker
- Capture source -> processing -> storage mappings and attach lineage metadata to events
