You are using PARSE DOCUMENT on documents stored in an external stage. You notice that some documents are skipped during processing without any explicit error messages. Which of the following could be the MOST likely reason(s) for this behavior, and how would you address it?
Correct Answer: B,C
Option B is a common cause, where unsupported format and permissions are key things to consider and `VALIDATE' helps ensure data is valid. Option C is also correct, because virtual warehouse suspension can interrupt processing and specifying the warehouse ensures it's used.
Option A, while relevant to performance, doesn't explain silent skipping unless the files grossly exceed limits. Option D is possible but less likely than B or C and harder to diagnose without specific error messages. Option E is less likely, because even if the content is not parseable, it still doesn't explain why document is skipped silently.
