> > Just a question, how to ensure that the semantics of these functions are consistent with those in SPARK? > > @macroguo-ghy I executed the Function Sqls in the spark engine. And checked the function Definition/OperandType/ReturnType is consistent with the Spark definition. Some functions have subtle differences for corner cases of the arguments. And Calcite tests often do *not* test the corner cases. I haven't checked Spark in particular, but we are writing a lot of tests for existing functions and we find lots of such cases. -- This is an automated message from the Apache Git Service.
