dlt explicitly documents schema evolution plus 'schema and data contracts' as a mechanism to control how upstream changes are handled rather than silently breaking loads, and dlt-docs-20 confirms automatic detection and adaptation to schema changes without losing pipeline velocity. Community feedback (dlt-comm-8) reflects a preference for stricter control, which is itself addressed by dlt's contract system, not a failure of it.

weight 1 · round to dltFivetran docs describe connectors that land data as structured destination tables with automatic schema handling and type mapping (docs-18, docs-33), history/soft-delete sync modes that manage deduplication and deletes (docs-35, docs-13), and transformation layers producing 'analytics-ready tables' (docs-25). This directly supports typed, deduplicated tables rather than raw JSON blobs.

dlt explicitly infers/normalizes schemas, handles nested data into typed relational tables, and supports merge/dedup via primary_key/merge_key upserts rather than raw JSON dumps, with a queryable dataset interface (SQL/dataframe/Ibis) for analytics engineers.
