A missing required column is a contract break, not a data error: confirm whether customer_id was renamed, dropped, or never delivered in the latest load, then restore it at the source or update every consumer and the contract together if the rename is intentional. Use when a schema validation failing because customer_…
Look the object up by listing the current workspace rather than trusting the stored id or name, remap the reference to the current id, and fail loudly when a listing has no match. Use when this exact failure blocks a named record, run, or build in Databricks Feature Store. Not for a different error message or general …
Incremental models duplicate keys when the unique_key does not match the real grain or when late data bypasses the merge: inspect the duplicates the run created, confirm the unique_key columns in the model configuration, and rebuild the affected window with a correct merge. Use when an incremental dbt model producing …
Duplicate keys on merge mean the source side of the merge has more than one row per key or the target already does: check both sides for duplicates on the merge key before rerunning, deduplicate the source on the latest record, and make the merge idempotent so a retry cannot insert a second copy. Use when a warehouse …
Diff the definition against the live source schema, fix the named field type or reference at its definition rather than at each consumer, and rebuild or revalidate in dependency order. Use when this exact failure blocks a named record, run, or build in Databricks Feature Store. Not for a different error message or gen…
