Optimizing Queries for Good Performance
In previous chapters, you have learned how to read system statistics and how to make use of what PostgreSQL provides. Armed with this knowledge, this chapter is all about good query performance. You will learn more about the following topics:
- Optimizer internals
- Execution plans
- Partitioning data
- Enabling and disabling optimizer settings
- Parameters for good query performance
At the end of the chapter, I hope that you will be able to write better and faster queries. And if your queries still happen to be bad, you should be able to understand why this is the case.
