And I thought that - maybe - if I change the list of columns with "select * from " in the property of the CA, the time it takes to pull the data will be reduced. But maybe it will be reduced by 1-2 seconds. And the customer is complaining of 30-40 seconds. So, for now, I will leave out this approach until I learn more.
