What is the purpose of the checkpoint location in a Structured Streaming pipeline that uses Auto Loader?

Question

Accepted Answer

C. It persists the stream''s processing progress and tracks which files have already been ingested to enable fault-tolerant, exactly-once processing. The checkpoint location is a critical component of any Structured Streaming pipeline. Databricks documentation states that Auto Loader uses the checkpoint location to store the names of all discovered files and the stream''s processing progress. On restart after a failure, the stream resumes from the last saved checkpoint position rather than reprocessing all files from the beginning, ensuring exactly-once delivery.
