Suggested answer: A, B

Explanation:

COPY_HISTORY Record Indicates Unloaded Subset of Files:

If the COPY_HISTORY function output indicates a subset of files was not loaded, you may try to "refresh" the pipe.

This situation can arise in any of the following situations:

· The external stage was previously used to bulk load data using the COPY INTO table command.

· REST API:

o External event-driven functionality is used to call the REST APIs, and a backlog of data files al-ready existed in the external stage before the events were configured.

· Auto-ingest:

o A backlog of data files already existed in the external stage before event notifications were configured.

o An event notification failure prevented a set of files from getting queued.

To load the data files in your external stage using the configured pipe, execute an ALTER PIPE … REFRESH statement.
