Data Lake Platform

Build and operate production data lakes and lakehouses: ingest, transform, store in open formats, and serve analytics reliably.

When to Use

• Design data lake/lakehouse architecture
• Set up ingestion pipelines (batch, incremental, CDC)
• Build SQL transformation layers (SQLMesh, dbt)
• Choose table formats and catalogs (Iceberg, Delta, Hudi)
• Deploy query/serving engines (Trino, ClickHouse, DuckDB)
• Implement streaming pipelines (Kafka, Flink)
• Set up orchestration (Dagster, Airflow, Prefect)
• Add governance, lineage, data quality, and cost controls

Triage Questions

1. Batch, streaming, or hybrid? What is the freshness SLO?
2. Append-only vs upserts/deletes (CDC)? Is time travel required?
3. Primary query pattern: BI dashboards (high concurrency), ad-hoc joins, embedded analytics?
4. PII/compliance: row/column-level access, retention, audit logging?
5. Platform constraints: self-hosted vs cloud, preferred engines, team strengths?

Default Baseline (Good Starting Point)

• Storage: object storage + open table format (usually Iceberg)
• Catalog: REST/Hive/Glue/Nessie/Unity (match your platform)
• Transforms: SQLMesh or dbt (pick one and standardize)
• Lake query: Trino (or Spark for heavy compute/ML workloads)
• Serving (optional): ClickHouse/StarRocks/Doris for low-latency BI
• Governance: DataHub/OpenMetadata + OpenLineage
• Orchestration: Dagster/Airflow/Prefect

Workflow

1. Pick table format + catalog: references/storage-formats.md (use assets/cross-platform/template-schema-evolution.md and assets/cross-platform/template-partitioning-strategy.md)
2. Design ingestion (batch/incremental/CDC): references/ingestion-patterns.md (use assets/cross-platform/template-ingestion-governance-checklist.md and assets/cross-platform/template-incremental-loading.md)
3. Design transformations (bronze/silver/gold or data products): references/transformation-patterns.md (use assets/cross-platform/template-data-pipeline.md)
4. Choose lake query vs serving engines: references/query-engine-patterns.md
5. Add governance, lineage, and quality gates: references/governance-catalog.md (use assets/cross-platform/template-data-quality-governance.md and assets/cross-platform/template-data-quality.md)
6. Plan operations + cost controls: references/operational-playbook.md and references/cost-optimization.md (use assets/cross-platform/template-data-quality-backfill-runbook.md and assets/cross-platform/template-cost-optimization.md)

• Data mesh (domain-owned data products): references/architecture-patterns.md
• Streaming-first (Kappa): references/streaming-patterns.md

Quick Start

dlt + ClickHouse

pip install "dlt[clickhouse]"
dlt init rest_api clickhouse
python pipeline.py

SQLMesh + DuckDB

pip install sqlmesh
sqlmesh init duckdb
sqlmesh plan && sqlmesh run

Reliability and Safety

Do

• Define data contracts and owners up front
• Add quality gates (freshness, volume, schema, distribution) per tier
• Make every pipeline idempotent and re-runnable (backfills are normal)
• Treat access control and audit logging as first-class requirements

Avoid

• Skipping validation to "move fast"
• Storing PII without access controls
• Pipelines that can't be re-run safely
• Manual schema changes without version control

Fact-Checking

• Use web search/web fetch to verify current external facts, versions, pricing, deadlines, regulations, or platform behavior before final answers.
• Prefer primary sources; report source links and dates for volatile information.
• If web access is unavailable, state the limitation and mark guidance as unverified.
