SPRKSCL1154

org.apache.spark.sql.functions.ceil

Message: org.apache.spark.sql.functions.ceil 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.ceil function, which has a workaround.

Scenario

Input

Below is an example of the org.apache.spark.sql.functions.ceil function, first used with a column name as an argument, then with a column object and finally with a column object and a scale.

val df = Seq(2.33, 3.88, 4.11, 5.99).toDF("value")
val result1 = df.withColumn("ceil", ceil("value"))
val result2 = df.withColumn("ceil", ceil(col("value")))
val result3 = df.withColumn("ceil", ceil(col("value"), lit(1)))

Output

The SMA adds the EWI SPRKSCL1154 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(2.33, 3.88, 4.11, 5.99).toDF("value")
/*EWI: SPRKSCL1154 => org.apache.spark.sql.functions.ceil has a workaround, see documentation for more info*/
val result1 = df.withColumn("ceil", ceil("value"))
/*EWI: SPRKSCL1154 => org.apache.spark.sql.functions.ceil has a workaround, see documentation for more info*/
val result2 = df.withColumn("ceil", ceil(col("value")))
/*EWI: SPRKSCL1154 => org.apache.spark.sql.functions.ceil has a workaround, see documentation for more info*/
val result3 = df.withColumn("ceil", ceil(col("value"), lit(1)))

Recommended fix

Snowpark has an equivalent ceil function that receives a column object as an argument. For that reason, the Spark overload that receives a column object as an argument is directly supported by Snowpark and does not require any changes.

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

For the overload that receives a column object and a scale, you can use the callBuiltin function to invoke the Snowflake builtin CEIL function. To use it, you should pass the string "ceil" as the first argument, the column as the second argument and the scale as the third argument.

val df = Seq(2.33, 3.88, 4.11, 5.99).toDF("value")
val result1 = df.withColumn("ceil", ceil(col("value")))
val result2 = df.withColumn("ceil", ceil(col("value")))
val result3 = df.withColumn("ceil", callBuiltin("ceil", col("value"), lit(1)))
