A Bronze-to-Silver pipeline requires data quality rules that drop invalid rows while recording metrics for monitoring. Stakeholders want declarative checks and managed lineage without hand‑coding UDF logic. Which option should you choose?

Use Delta Live Tables (DLT) with declarative EXPECT clauses. In DLT you define a table with an EXPECT statement such as EXPECT or_drop or EXPECT or_fail to enforce data quality. The framework automatically tracks metrics in the DLT event log, provides lineage, and drops or quarantines rows that violate the rule. This approach eliminates the need for custom UDFs, keeps the pipeline declarative, and gives stakeholders visibility into quality metrics.
