Exam DBDEA Topics: ingestion Difficulty: hard

A data provider delivers files inside a Hive-style directory layout — year=2026/month=10/day=27/part-001.json — and the ingestion team wants the year, month, and day values to become real columns of the target table without parsing file paths by hand. Which Auto Loader capability provides this?

Options (Reading Mode) Click to filter discussion →
  1. A. pathGlobFilter, with a glob pattern per date component applied once per ingestion
  2. B. A UDF that splits the input path column on the equals sign and the year, month, and day tokens in every file
  3. C. Partition inference: Auto Loader derives partition columns from the directory layout of the files
  4. D. It is not possible, because directory layout information is discarded during ingestion
