Support null foreign keys in get_random_subset #2056

Open gsheni opened 2 weeks ago

gsheni commented 2 weeks ago

Problem Description

Currently, get_random_subset raises a warning if it detects null foreign keys.
To support null foreign keys in SDV, we would like to remove this warning and change the behavior of get_random_subset to allow null foreign keys to be subsampled.

Expected behavior

A user can use get_random_subset with null foreign keys.
The user does not get an error or warning with null foreign keys.
The user can expect that subsampled data returned from get_random_subset may contain null foreign keys, if present in the input data.
