########## datafusion/datasource/src/file_scan_config/mod.rs: ########## Review Comment: Yes. We would have to take the column parttion values, sort them, and represent them as a range partitioning where each partition only contains the intended values. Example: ```text partition 1: col = A partition 2: col = Z partition 3: col = M ``` Represented like: ```text Range Partitioning: split points: [A, M, Z] sort order: Asc ``` Thus: ```text partition 1: col <= B parttion 2: A < col <= M partition 3: M <= col (which contains Z) ``` -- This is an automated message from the Apache Git Service.
