Selecting the needed objects

Although we offer you the opportunity to select all of the objects in the Salesforce data source, we recommend that you only bring in the data that you actually need.  There are several reasons for this.

1. Every table that you create counts against your storage tier. Having redundant tables that you will not use is a waste of storage in your account.
2. The more objects you select the longer it will take for the data source to complete. When you select only the ones that you need, the data source will run faster.
3. Salesforce is limiting the number of API calls that you can make on your account. The more objects you select, the more API calls are needed.
