SPRKSCL1113

org.apache.spark.sql.functions.next_day

Message: org.apache.spark.sql.functions.next_day has a workaround, see documentation for more info

Category: Warning

Description

This issue appears when the SMA detects a use of the org.apache.spark.sql.functions.next_day function, which has a workaround.

Scenario

Input

Below is an example of the org.apache.spark.sql.functions.next_day function, first used with a string as the second argument and then with a column object.

val df = Seq("2024-11-06", "2024-11-13", "2024-11-20").toDF("date")
val result1 = df.withColumn("next_monday", next_day(col("date"), "Mon"))
val result2 = df.withColumn("next_monday", next_day(col("date"), lit("Mon")))

Output

The SMA adds the EWI SPRKSCL1113 to the output code to let you know that this function is not fully supported by Snowpark, but it has a workaround.

val df = Seq("2024-11-06", "2024-11-13", "2024-11-20").toDF("date")
/*EWI: SPRKSCL1113 => org.apache.spark.sql.functions.next_day has a workaround, see documentation for more info*/
val result1 = df.withColumn("next_monday", next_day(col("date"), "Mon"))
/*EWI: SPRKSCL1113 => org.apache.spark.sql.functions.next_day has a workaround, see documentation for more info*/
val result2 = df.withColumn("next_monday", next_day(col("date"), lit("Mon")))

Recommended fix

Snowpark has an equivalent next_day function that receives two column objects as arguments. For that reason, the Spark overload that receives two column objects as arguments is directly supported by Snowpark and does not require any changes.

For the overload that receives a column object and a string, you can convert the string into a column object using the com.snowflake.snowpark.functions.lit function as a workaround.

val df = Seq("2024-11-06", "2024-11-13", "2024-11-20").toDF("date")
val result1 = df.withColumn("next_monday", next_day(col("date"), lit("Mon")))
val result2 = df.withColumn("next_monday", next_day(col("date"), lit("Mon")))
