Research direction
The issue names DataX, MySQL synchronization, and an empty file in a partition, but provides no source file, test, or entry point. Start by reproducing the failure with an empty partition file and trace the column-reading path that produces columnIndexMax < 0 and column: []. Done means empty partition files are handled without this error and existing non-empty synchronization still works.
