Salesforce Certified Data Architecture Practice Test

To improve the performance of SOQL queries on the Order_c object, what is a valid approach?

1. Use SOQL queries without WHERE conditions.

2. Work with Salesforce Support to enable Skinny Tables.

3. Reduce the number of triggers on the Order_c object.

4. Make the queries more selective using indexed fields.

The correct answer is: Work with Salesforce Support to enable Skinny Tables.

The best approach to improve the performance of SOQL queries on the Order_c object is to make the queries more selective using indexed fields. When you leverage indexed fields in your queries, Salesforce can retrieve the relevant records more efficiently. Indexed fields significantly enhance the speed of data retrieval because they allow the system to quickly locate the desired data without scanning every row in the table. For example, if a query involves a field that is indexed, Salesforce can pinpoint the records that meet the criteria through optimized querying, resulting in faster response times. This holds particular importance when working with large datasets, where queries can become slow and unresponsive if not structured properly. Using indexed fields effectively ensures that the queries are not only faster but also less resource-intensive, leading to better overall application performance. While making use of skinny tables can also improve performance, it typically involves working through Salesforce Support and may not always be necessary depending on the specific use case.
