#1185 is also a follow up to #1139 that is closely related to this. Maybe we can merge the two issues and create subtasks? @alamb my idea was that each standard/technique for getting the list of files (table catalog) should be a different provider. The `ListingTable` provider might handle folder structures that are slightly different from the hive one (e.g `mytable/2021/11/02` instead of `mytable/year=2021/month=11/day=02`), but it focuses on setups where the partitions are encoded in the folder structure itself and are discovered by **"listing"** the file system. Most of the code inside the `datasource/listing` module should be specialized to do precisely that (e.g chose a listing strategy, parse the paths...). Everything else can (should 😉) be taken out and mutualized into a common module for reuse in other table providers 😊. -- This is an automated message from the Apache Git Service.
