Production projects
- Columnar Real-Time Analytical Database (OLAP) Classic ClickHouse A single CMake super-project that vendors ~150 native dependencies (Arrow, gRPC, AWS/Azure/GCS SDKs, NuRaft, Delta Lake kernel) under contrib/ lets ClickHouse ship a largely self-contained, dependency-free binary and Docker image.
- Billing & Metering Engine Classic Lago Usage-event ingestion and pricing-expression evaluation are pulled out of the Rails request/response cycle into a dedicated Go service and a shared Rust library, so billing-critical event throughput scales independently of the API that serves the dashboard and public API.
- Developer Data Platform Classic Crowd.dev Decomposing ingestion, enrichment, and merging into many independent Temporal-orchestrated worker services under services/apps lets crowd.dev scale each pipeline stage separately, while shared @crowd/* libraries keep database, queue, search, and cache access consistent across all of them.
- Error Tracking Platform Classic Sentry Pairing Django with Kafka and ClickHouse allows Sentry to ingest billions of events daily while providing sub-second analytical search across production traces.
- Product Analytics Platform Hybrid PostHog Pairing Apache Kafka with ClickHouse columnar storage enables PostHog to ingest billions of monthly events while maintaining sub-second query response times.
