In Spark , sort, and orderBy functions of the DataFrame are used to sort multiple DataFrame columns, you can also specify asc for ascending and desc for descending to specify the order of the sorting.
When sorting on multiple columns, you can also specify certain columns to sort on ascending and certain columns on descending.
1. Using sort() to sort multiple columns
In Spark, We can use sort() function of the DataFrame to sort the multiple columns. If you wanted to ascending and descending, use asc and desc on Column.
// Using sort() to sort multiple columns
df.sort("department","state")
df.sort(col("department").asc,col("state").desc)
2. Using orderBy() to sort multiple columns
Alternatively, we can also use orderBy() function of the DataFrame to sort the multiple columns. and use asc for ascending and desc for descending.
// Using orderBy() to sort multiple columns
df.orderBy("department","state")
df.orderBy(col("department").asc,col("state").desc)
