### What is the problem the feature request solves? Follow up for #5323 The merge opens every file in the partition at once, and each open file allocates an Arrow read buffer. Partitions with a very large number of files can run out of memory on large datasets. ### Describe the potential solution read a fixed number of files at a time instead of all of them, and order which files to read first by some stats (or another signal), while still producing correct merged order. ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
