Hi @silence-coding Without an `ORDER BY` clause, the query engine is free to return the rows in any order. The reason it is returning the rows in different order is the parallel execution of DataFusion: execution on one file/partition might finish sooner than the other, returning the rows earlier. -- This is an automated message from the Apache Git Service.
