104: Jonathan Reinink - Pushing More Work to the Database

In this episode, Adam talks to Jonathan Reinink about strategies for off-loading resource intensive work from your application code and into your database.

Topics include:
  • Issues you run into when you do too much work in code instead of in the database
  • Why memory usage is just as important as query count
  • How being smarter with your database usage can let you avoid hard problems like cache invalidation
  • Denormalizing computable data to make it queryable
  • Using "where not exists" strategically to improve query performance
  • Why the solution to n+1 problems isn't always as simple as eager-loading
  • How subqueries work and how you can use them to avoid memory problems when eager-loading
