Auto Loader incrementally and efficiently processes new data files as they arrive in cloud storage without any additional setup. Auto Loader provides a new Structured Streaming source called
cloudFiles. Given an input directory path on the cloud file storage, the
cloudFiles source automatically processes new files as they arrive, with the option of also processing existing files in that directory. For details, see Load files from S3 using Auto Loader.
