SPRKPY1031

pyspark.sql.column.Column.contains

This issue code has been deprecated since Spark Conversion Core 2.7.0

Message: pyspark.sql.column.Column.contains has a workaround, see documentation for more info

Category: Warning

Description

This issue appears when the SMA detects a use of the pyspark.sql.column.Column.contains function, which has a workaround.

Scenario

Input

Below is an example of a use of the pyspark.sql.column.Column.contains function that generates this EWI. In this example, the contains function is used to filter the rows where the 'City' column contains the substring 'New'.

df = spark.createDataFrame([("Alice", "New York"), ("Bob", "Los Angeles"), ("Charlie", "Chicago")], ["Name", "City"])
df_filtered = df.filter(col("City").contains("New"))

Output

The SMA adds the EWI SPRKPY1031 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([("Alice", "New York"), ("Bob", "Los Angeles"), ("Charlie", "Chicago")], ["Name", "City"])
#EWI: SPRKPY1031 => pyspark.sql.column.Column.contains has a workaround, see documentation for more info
df_filtered = df.filter(col("City").contains("New"))

Recommended fix

As a workaround, you can use the snowflake.snowpark.functions.contains function by passing the column as the first argument and the element to search as the second argument. If the element to search is a literal value then it should be converted into a column expression using the lit function.

from snowflake.snowpark import functions as f
df = spark.createDataFrame([("Alice", "New York"), ("Bob", "Los Angeles"), ("Charlie", "Chicago")], ["Name", "City"])
df_filtered = df.filter(f.contains(col("City"), f.lit("New")))
