Скачать или смотреть Data Architecture: Using the Query Plan Tool to Understand Query Performance

We are going to be diving into Data Architecture, and a key element is having queries that can execute with good performance. To achieve this in Salesforce, especially as the data volumes grow, you need to understand some key elements such as:

Query Optimizer
Selective Queries
Indexes
Query Plan Tool

One of the first places to start is to enable the Query Plan Tool and start to view the information it provides. In this video, I introduce the Query Plan Tool and how to enable it. I then run a few different Queries, showing the values returned.

This video is in the Salesforce Data Architect Set.
