01Summary
Unlike CDC pipelines, it avoids second databases or replicated tables. Access paths are optimized by format: heap pages for point lookups, Parquet for scans. No independent catalog or table exists beyond the primary store, ensuring consistency and eliminating data drift risks.

02Key points
- LTAP maintains one durable data copy in the lake, not a second database.
- Caching layers (e.g., Postgres buffers) are performance tiers, not replicas.
- Point lookups use heap pages; scans use Parquet — both lossless and optimized.
- No CDC pipeline or secondary table exists, preventing data drift and inconsistency.
