Auditing clarifies what a data platform must deliver before architecture, vendors, infrastructure, or deployment models are selected. It connects stakeholder discovery to actionable requirements and reduces the risk of optimizing for the wrong problem. section 4.1
A lakehouse audit can combine:
- Immutable Iceberg snapshots recording commits, timestamps, files, operations, and user identifiers. section 11.2
- Schema-history inspection for added, removed, or changed fields and data types. section 11.2
- Catalog, query-engine, and lineage integrations for tracing access, usage, and downstream data flow. section 11.2 section 11.2.7
Inspecting recent table activity
Query snapshot metadata ordered by commit time to identify the latest operations and their associated users: SELECT snapshot_id, operation, committed_at, user_id FROM my_catalog.db.table.snapshots ORDER BY committed_at DESC; section 11.2.7
