Inspect inferred schemas and rescued or null fields in recently ingested rows. This diagnose action addresses a different case (nested json ingest), where the initial reader assumes one unchanging flat schema and loses new fields. Explicit schema management and rescued data handling protect evolving semi-structured ingestion. In the stated problem, an XML ingest incorrectly flattens multiple line items into one text field; this choice would not establish the required xml repeating elements decision.

Inspect duplicate file IDs and the ingestion checkpoint state. This diagnose action addresses a different case (retry-safe file loads), where a partially processed input file is loaded twice into Delta. Checkpointed incremental ingestion or stable event-level deduplication prevents repeated effects. In the stated problem, an XML ingest incorrectly flattens multiple line items into one text field; this choice would not establish the required xml repeating elements decision.

Inspect file media types and current input source format. This diagnose action addresses a different case (binary payload metadata), where a line-oriented text reader corrupts the raw binary payload. binaryFile input preserves raw file bytes and path metadata rather than decoding lines. In the stated problem, an XML ingest incorrectly flattens multiple line items into one text field; this choice would not establish the required xml repeating elements decision.

Verify production tasks receive the production catalog and input paths. This validate action addresses a different case (bundle target overrides), where development job arguments were deployed into the production target. Bundle targets can override environment-specific variables and resource settings. In the stated problem, the downstream write repeats non-idempotent side effects on retry; this choice would not establish the required job retry semantics decision.

Reverse input arrival order and verify identical final target state. This validate action addresses a different case (cdc duplicate sequence), where the processing order for tied source events is nondeterministic. A deterministic sequencing contract needs a unique ordered event position. In the stated problem, the downstream write repeats non-idempotent side effects on retry; this choice would not establish the required job retry semantics decision.

Verify the job authenticates without the token appearing in code or logs. This validate action addresses a different case (secure configuration), where an API token is committed in a Python notebook tracked in Git. Secret-backed configuration avoids embedding credentials in notebooks or deployment YAML. In the stated problem, the downstream write repeats non-idempotent side effects on retry; this choice would not establish the required job retry semantics decision.

Confirm deployment works while a developer cannot grant themselves table access. This validate action addresses a different case (separation of duties), where all developers currently own production catalogs and can grant access. Separate deploy and governance roles reduce accidental privilege escalation. In the stated problem, granting SELECT on the raw fact table violates minimization; this choice would not establish the required secure view sharing decision.

Confirm equal source IDs map to equal pseudonyms without exposing originals. This validate action addresses a different case (pseudonymized join keys), where a naive hash without controlled key management risks predictable identifiers. Keyed pseudonymization can preserve joins while reducing identifier exposure. In the stated problem, granting SELECT on the raw fact table violates minimization; this choice would not establish the required secure view sharing decision.

Query the export view and confirm prohibited fields are absent. This validate action addresses a different case (sensitive data suppression), where a broad SELECT still includes unstructured notes. Column suppression and data minimization prevent unnecessary sensitive-field release. In the stated problem, granting SELECT on the raw fact table violates minimization; this choice would not establish the required secure view sharing decision.

Create a historical failure and runtime dashboard by workflow. This design action addresses a different case (job operational history), where operators only see the most recent run in the Jobs UI. Jobs system records support historical analysis of runs and tasks. In the stated problem, cost reports omit some job and workspace labels; this choice would not establish the required billing usage monitoring decision.

Design an approved incident destination for failed job events. This design action addresses a different case (job webhook destination), where only personal email notifications are configured. Supported job notification destinations can integrate workflow status with an incident system. In the stated problem, cost reports omit some job and workspace labels; this choice would not establish the required billing usage monitoring decision.

Define an alert query counting missing active units. This design action addresses a different case (sql alert threshold), where the current dashboard has no automated alert for missing units. SQL alerts can evaluate a query result against a configured threshold. In the stated problem, cost reports omit some job and workspace labels; this choice would not establish the required billing usage monitoring decision.

Rewrite the federated query to preserve pushdown-compatible predicates. This implement action addresses a different case (federated pushdown), where an analyst pulls millions of rows before a selective filter. Supported predicate pushdown can reduce data transferred from a federated source. In the stated problem, catalog discovery was mistaken for full table access; this choice would not establish the required foreign catalog permission decision.

Rotate the recipient credential according to the supported sharing workflow. This implement action addresses a different case (sharing credential rotation), where partners risk losing access or using a leaked long-lived credential. Credential rotation must be coordinated without unnecessarily broadening permissions. In the stated problem, catalog discovery was mistaken for full table access; this choice would not establish the required foreign catalog permission decision.

Create a supported connection and foreign catalog with least-privilege credentials. This implement action addresses a different case (federated connection), where engineers export the full source database into cloud object storage each hour. Lakehouse Federation can query supported external sources through a catalog connection. In the stated problem, catalog discovery was mistaken for full table access; this choice would not establish the required foreign catalog permission decision.

Inspect the unit-coverage query and expected threshold. This diagnose action addresses a different case (sql alert threshold), where the current dashboard has no automated alert for missing units. SQL alerts can evaluate a query result against a configured threshold. In the stated problem, no baseline is available for the warehouse query execution; this choice would not establish the required sql query history decision.

Inspect source offsets, processed offsets and per-batch duration. This diagnose action addresses a different case (streaming backlog), where consumer lag grows while microbatch intervals appear stable. Backlog growth reveals insufficient sustainable processing throughput. In the stated problem, no baseline is available for the warehouse query execution; this choice would not establish the required sql query history decision.

Inspect Query Profile operators for scan volume and pruning. This diagnose action addresses a different case (query profile scans), where operators assume the query is always CPU-bound. Query Profile identifies scan, pruning and shuffle behavior for SQL workloads. In the stated problem, no baseline is available for the warehouse query execution; this choice would not establish the required sql query history decision.

Add meaningful table and column comments through supported metadata commands. This implement action addresses a different case (catalog descriptions), where table and column metadata lack meaningful descriptions. Unity Catalog comments improve discoverability of governed data assets. In the stated problem, investigators cannot tell which upstream transformation produced it; this choice would not establish the required lineage tracking decision.

Transfer ownership to the approved group under supported permissions. This implement action addresses a different case (ownership reassignment), where new data stewards cannot maintain its grants. Unity Catalog ownership should be assigned to a maintained principal. In the stated problem, investigators cannot tell which upstream transformation produced it; this choice would not establish the required lineage tracking decision.

Set the supported managed location and create tables under it. This implement action addresses a different case (managed storage ownership), where the data platform cannot apply consistent lifecycle governance. Managed locations centralize storage ownership for Unity Catalog managed assets. In the stated problem, investigators cannot tell which upstream transformation produced it; this choice would not establish the required lineage tracking decision.

Use a governed connection and foreign catalog for appropriate federated reads. This design action addresses a different case (federated connection), where engineers export the full source database into cloud object storage each hour. Lakehouse Federation can query supported external sources through a catalog connection. In the stated problem, consumers assume the share is a nightly static export; this choice would not establish the required shared table freshness decision.

Define a minimal table-level share membership contract. This design action addresses a different case (share catalog scope), where the recipient can discover unintended datasets. A Delta Sharing share should contain only explicitly approved assets. In the stated problem, consumers assume the share is a nightly static export; this choice would not establish the required shared table freshness decision.

Choose D2D sharing for supported Databricks managed recipients. This design action addresses a different case (d2d managed recipient), where a recipient team copies files manually and loses timely updates. Databricks-to-Databricks Delta Sharing supports governed live access without manual copying. In the stated problem, consumers assume the share is a nightly static export; this choice would not establish the required shared table freshness decision.

Confirm users can discover metadata but cannot read restricted table rows. This validate action addresses a different case (browse metadata privilege), where teams grant SELECT merely to expose object listings. BROWSE enables controlled metadata discovery without granting data read access. In the stated problem, naming conventions alone are inconsistent across teams; this choice would not establish the required governed tags decision.

Confirm stewards can manage the table while readers retain intended access. This validate action addresses a different case (ownership reassignment), where new data stewards cannot maintain its grants. Unity Catalog ownership should be assigned to a maintained principal. In the stated problem, naming conventions alone are inconsistent across teams; this choice would not establish the required governed tags decision.

Search Catalog Explorer and verify definitions distinguish the assets. This validate action addresses a different case (catalog descriptions), where table and column metadata lack meaningful descriptions. Unity Catalog comments improve discoverability of governed data assets. In the stated problem, naming conventions alone are inconsistent across teams; this choice would not establish the required governed tags decision.

Inspect pip resolution output and the installed dependency tree. This diagnose action addresses a different case (library version pinning), where a transitive dependency updated to an incompatible version. Explicit compatible dependency versions improve reproducibility across new compute environments. In the stated problem, dependent tasks sometimes run before the bronze load finishes; this choice would not establish the required job task dag decision.

Inspect per-key sequence collisions and upstream log offsets. This diagnose action addresses a different case (cdc duplicate sequence), where the processing order for tied source events is nondeterministic. A deterministic sequencing contract needs a unique ordered event position. In the stated problem, dependent tasks sometimes run before the bronze load finishes; this choice would not establish the required job task dag decision.

Inspect task invocation mode and module entrypoint expectations. This diagnose action addresses a different case (python task entrypoints), where the task exits before setting up its argument parser. A standard Python entrypoint and explicit arguments avoid notebook runtime assumptions. In the stated problem, dependent tasks sometimes run before the bronze load finishes; this choice would not establish the required job task dag decision.

Verify recipient sees the selected dataset but not excluded tables. This validate action addresses a different case (share catalog scope), where the recipient can discover unintended datasets. A Delta Sharing share should contain only explicitly approved assets. In the stated problem, a recipient team copies files manually and loses timely updates; this choice would not establish the required d2d managed recipient decision.

Confirm the partner reads only the approved shared dataset. This validate action addresses a different case (open protocol recipient), where the partner cannot use an internal Databricks-to-Databricks credential flow. Open Delta Sharing can support non-Databricks recipients using the sharing protocol. In the stated problem, a recipient team copies files manually and loses timely updates; this choice would not establish the required d2d managed recipient decision.

Compare remote rows scanned and local query results before and after. This validate action addresses a different case (federated pushdown), where an analyst pulls millions of rows before a selective filter. Supported predicate pushdown can reduce data transferred from a federated source. In the stated problem, a recipient team copies files manually and loses timely updates; this choice would not establish the required d2d managed recipient decision.
