An analyst needs to append only the Parquet files in a specific object-storage folder to a registered Delta table using SQL.
Which acceptance result most directly demonstrates that the intended solution works?
COPY INTO loads matching storage files into an existing target while honoring the declared input format.
New JSON objects arrive in the bronze target once per discovery cycle without rescanning and reloading the full historical folder. That finding does not establish that only the Parquet files in the selected folder contribute new rows to the target table.
After restarting ingestion the previously inferred schema and newly approved columns remain recognized. That finding does not establish that only the Parquet files in the selected folder contribute new rows to the target table.
A new unknown input attribute appears in rescued data rather than in the registered table schema. That finding does not establish that only the Parquet files in the selected folder contribute new rows to the target table.
A telemetry service drops tens of thousands of small JSON files throughout the day and the ingestion service must discover new arrivals incrementally.
Which implementation decision best addresses this requirement?
Auto Loader is designed for scalable incremental discovery in object-storage file ingestion workloads. The selected implementation is the one directly aligned with the constraints in the scenario.
A Structured Streaming checkpoint records processed progress and is necessary to resume the logical stream reliably.
Auto Loader can preserve fields that cannot be parsed under the inferred schema in a rescue JSON structure.
Fail-on-new-columns prevents unreviewed schema expansion instead of silently accepting the upstream change.

Which acceptance result most directly demonstrates that the intended solution works?
Auto Loader is designed for scalable incremental discovery in object-storage file ingestion workloads.
The restarted stream continues from recorded progress and ingests only newly discovered files. That finding does not establish that new JSON objects arrive in the bronze target once per discovery cycle without rescanning and reloading the full historical folder.
A malformed typed field appears with its source details in _rescued_data while valid fields remain available. That finding does not establish that new JSON objects arrive in the bronze target once per discovery cycle without rescanning and reloading the full historical folder.
A file containing an unapproved column stops ingestion until the schema contract is deliberately revised. That finding does not establish that new JSON objects arrive in the bronze target once per discovery cycle without rescanning and reloading the full historical folder.
An Auto Loader stream is restarted after a driver replacement and must not replay every file already committed to the destination.
Which implementation decision best addresses this requirement?
A Structured Streaming checkpoint records processed progress and is necessary to resume the logical stream reliably. The selected implementation is the one directly aligned with the constraints in the scenario.
The schema location retains schema inference and evolution metadata separately from ordinary destination table data.
Auto Loader can append new columns to its tracked schema before stopping the stream for restart under addNewColumns.
Identifier preservation requires controlling the inferred data type rather than relying on parsing heuristics.

After restarting ingestion the previously inferred schema and newly approved columns remain recognized. That finding does not establish that the restarted stream continues from recorded progress and ingests only newly discovered files.
After restart the new property appears as a target column while earlier rows still load normally. That finding does not establish that the restarted stream continues from recorded progress and ingests only newly discovered files.
An identifier such as 00073 stays exactly five characters in the bronze table. That finding does not establish that the restarted stream continues from recorded progress and ingests only newly discovered files.
JSON files now include optional customer preferences and the engineer wants Auto Loader to remember its inferred schema across runs.

Auto Loader can preserve fields that cannot be parsed under the inferred schema in a rescue JSON structure.
The rescue mode preserves schema stability while recording new or mismatched fields separately instead of evolving columns.
The binary file source exposes paths and payload content rather than interpreting every object as a tabular JSON record.

An image arrives with its file metadata and binary payload intact in the downstream extraction process. That finding does not establish that after restarting ingestion the previously inferred schema and newly approved columns remain recognized.
Several producers sometimes send string values in a JSON field normally represented as an integer, and engineers must inspect those mismatches later.

Fail-on-new-columns prevents unreviewed schema expansion instead of silently accepting the upstream change.
Keeping nested payloads at the ingestion boundary preserves source fidelity for later transformations.

A sample record retains its array and nested object fields in bronze and can be exploded downstream. That finding does not establish that a malformed typed field appears with its source details in _rescued_data while valid fields remain available.
An Auto Loader JSON source introduces a previously unseen optional property, and operations accept a controlled stream restart when schema changes.

Without the correct CSV reader option, the heading line can be parsed as a normal data record.

The column names match the header and the header text is absent from the target data rows. That finding does not establish that after restart the new property appears as a target column while earlier rows still load normally.
