PNDSPY1004¶

Message Pandas < element > has a direct mapping, but it’s restricted to running on a single node. As a result, performance may be impacted, especially with large datasets.

Category Warning

Description¶

This issue appears when the SMA detects the use of a pandas element that has a direct equivalent in Snowpark pandas, but it’s restricted to running on a single node, so its performance may be impacted.

Scenario¶

A method that runs on a single node.

Input¶

The following example shows a method that runs on a single node.

import pandas as pd

ser = pd.Series([1, 2, 3, 3])
ser.plot(kind='hist', title="My plot")

Output¶

The SMA adds the EWI PNDSPY1004 to the output code to let you know that this element runs on a single node, and its performance may be impacted.

import snowflake.snowpark.modin.pandas as pd

ser = pd.Series([1, 2, 3, 3])
#EWI: PNDSPY1004 => pandas.core.series.Series.plot has a direct mapping, but it's restricted to running on a single node. As a result, performance may be impacted,
especially with large datasets.
ser.plot(kind='hist', title="My plot")

Recommended fix¶

Since this is a generic error code that applies to a range of partially supported functions, no single recommended fix exists.

Additional recommendations¶

Check the Snowpark pandas documentation to verify the pandas elements that run on a single node.
