In this workshop, you'll learn to leverage powerful Active Record capabilities to bring your applications to the next level. We'll start from scratch and focus on two major areas. We’ll work with high performance queries and we’ll configure and use multiple databases.
You’ll learn how to write efficient queries with good visibility from your Active Record code. You’ll use a variety of index types to lower the cost and improve the performance of your queries. You'll use query planner info with Active Record.
Next we'll shift gears into multi-database application design. You'll introduce a second database instance, set up replication between them, and configure Active Record for writer and reader roles. With that in place, you’ll configure automatic role switching.
