Filter out null values in source column used for deriving partitions for final table
A null value in a source column that is used to derive partition for the final table leads to an empty WHERE clause in query generation at merge step. Prevent this situation.
(Reference: Look at where this behavior was identified)
A validation will be added for source columns that are used for deriving partitions. If this has been configured during feed setup, it will be used instead. As a result, rows containing null values for these columns will be identified as invalid and not processed further.
