@szehon-ho, the reason why we use `all_manifests` is to avoid the expensive driver-side manifest list file reads. `all_files` has to read through every manifest list in the table from the driver to find all the manifests, dedup, and then make tasks. The `all_manifests` table makes a task out of each manifest list to produce a collection of manifests from just the list of snapshots/manifest lists. -- This is an automated message from the Apache Git Service.
