To ensure data type consistency, you can use the CAST function to convert the data types of join keys in subqueries. Sample statements: create table T0(c0 int, c1 int, c2 int, c3 int); create table T1(c0 string, c1 int, c2 int); -- Method 1: select /*+ skewjoin(a) */ * ...
In this code, we first define a salt value, which can be a random integer or any other value. We then add a salt column to our DataFrame using the withColumn() function, where we set the value of the salt column to a random number using the rand() function with a fixed seed. The...
