14⟩ can u explain one critical mapping? performance issue which one is better? whether connected lookup tranformation or unconnected one?

It depends on your data and the type of operation your doing.

If you need to calculate a value for all the rows or for the maximum rows coming out of the source then go for a connected lookup.Or,if it is not so then go for unconnectd lookup.Specially in conditional case like,we have to get value for a field 'customer' from order tabel or from customer_data table,on the basis of following rule:

If customer_name is null then ,customer=customer_data.ustomer_Id

otherwise

customer=order.customer_name.

So in this case we will go for unconnected lookup
