Hi Debayan,

In the documentation, I see a paragraph "Create a TrainingSet when lookup keys do not match the primary keys".

The join must be done on all the columns of the primary key, we indicate the columns of the dataframe respecting the order of columns in primary keys, but we cannot do a partial join on the first column otherwise I get an error message.

To do this join, I use the read_table function to read the data from the feature store table and enrich the input dataframe before lookup engine.

But it's not satisfying.

Best regards
