# Proposed changes Issue Number: close #xxx ## Problem summary In previous implementation, when querying tvf, FE will get schema from BE. And BE will try to open the first file to get its schema info, but for orc or parquet format, if the file is empty, it will return error. But even for an empty file, we can still get schema info from file's footer. So we should handle the empty file to get schema info correctly. Also modify the catalog doc to add some FAQ. ## Checklist(Required) * [ ] Does it affect the original behavior * [ ] Has unit tests been added * [ ] Has document been added or modified * [ ] Does it need to update dependencies * [ ] Is this PR support rollback (If NO, please explain WHY) ## Further comments If this is a relatively large or complex change, kick off the discussion at [d...@doris.apache.org](mailto:d...@doris.apache.org) by explaining why you chose the solution you did and what alternatives you considered, etc... -- This is an automated message from the Apache Git Service.
