when digging deeper, this condition compares the struct with order this condition checks the schema order & data types as struct `if table_schema.as_struct() != task_schema.as_struct()` if the dataframe which is send to append don't have the columns in order w.r.t to the schema table, write fails because the struct turns about to be this table schema - struct<1: a: optional timestamptz, 2: b: optional timestamptz, 3: x: optional string, 4: y: optional string> (table columns in this order a, b,x,y) dataframe schema - struct<1: a: optional timestamptz, 2: b: optional timestamptz, y: optional string, 3: x: optional string, 4:> (dataframe columns in this order a,b,y,z) I think schema validation can be applied to data types of columns instead of order or error message could be more helpful mismatch of fields doesn't make sense here? thanks -- This is an automated message from the Apache Git Service.
