Very good question @crepererum , it may due to: In DataFusion’s SQL grammar, any identifier immediately following a table reference can be taken as an alias, and if it’s followed by BY col1, col2… it’s treated as a distribution hint (i.e. “hash‑partition on these columns”) rather than a typo of ORDER BY? That syntax (FROM <table> <alias> BY <cols>) is perfectly valid, there’s no parse or validation error... I need to investigate more, if we can have a better solution to solve this, thanks ! -- This is an automated message from the Apache Git Service.
