We use these techniques a lot to optimize our customers PostgreSQL databases with billions of data points during Cube. To keep it easy, we ran examples for this article on a test dataset.
The ability to see indexes is the first step to learning PostgreSQL query optimization. One index per query Indexes are materialized copies of your table. Rows Removed by Filter: Planning time: 0. Execution time: 0. Heap Fetches: 0. Group Key: orders. Sort Key: orders. Sort Method: quicksort Memory: 25kB.
