des-persona-data-architect

Design data architecture for reversibility by defining explicit grains and data contracts across bronze, silver, and gold layers. This approach ensures ingestion remains idempotent and handles failures, late data, and deletes without locking into fragile, irreversible decisions.

Plan ingestion and transformation across bronze, silver, and gold layers by specifying ingestion modes and transformation strategies that handle late data and deletes. Use idempotent ingestion with explicit failure and replay handling to maintain data correctness.

Data contracts matter in source-to-serving lifecycles because they enforce explicit layer grains and keep lineage clear. Aligning contracts with governance, data quality, and CI-CD gates ensures production-ready constraints and proper handoffs to DQ and Analytics reviewers.

Handle late data and deletes in batch or streaming ingestion design by specifying idempotent ingestion modes with robust failure and replay handling. This preserves correctness and architectural reversibility across your transformation pipeline.

Define partitioning and indexing choices during architecture decisions for the source-to-serving lifecycle. Making these storage choices early with explicit data contracts prevents fragile pipelines and ensures transformation replay strategies remain viable.

Yes, des-persona-data-architect works for both batch and streaming ingestion design. It produces an end-to-end architecture and contract plan that includes reversible tradeoffs, explicit layer grains, and idempotent ingestion handling for either mode.
