SPRKPY1022

pyspark.sql.functions.log10

Message: pyspark.sql.functions.log10 has a workaround, see documentation for more info

Category: Warning

Description

This issue appears when the SMA detects a use of the pyspark.sql.functions.log10 function, which has a workaround.

Scenario

Input

Below is an example of a use of the pyspark.sql.functions.log10 function that generates this EWI. In this example, the log10 function is used to calculate the base-10 logarithm of the value column.

df = spark.createDataFrame([(1,), (10,), (100,), (1000,), (10000,)], ["value"])
df_with_log10 = df.withColumn("log10_value", log10(df["value"]))

Output

The SMA adds the EWI SPRKPY1022 to the output code to let you know that this function is not directly supported by Snowpark, but it has a workaround.

df = spark.createDataFrame([(1,), (10,), (100,), (1000,), (10000,)], ["value"])
#EWI: SPRKPY1022 => pyspark.sql.functions.log10 has a workaround, see documentation for more info
df_with_log10 = df.withColumn("log10_value", log10(df["value"]))

Recommended fix

As a workaround, you can use the snowflake.snowpark.functions.log function by passing the literal value 10 as the base.

df = spark.createDataFrame([(1,), (10,), (100,), (1000,), (10000,)], ["value"])
df_with_log10 = df.withColumn("log10_value", log(10, df["value"]))
