Extreme optimization of Postgres - speeding up queries by around 200x
In the article on the Spacelift blog, the author discusses various techniques that can be used to enhance the performance of queries in PostgreSQL databases. Specifically, it focuses on how to ‘trick’ the PostgreSQL query planner to improve the selection of query plans, potentially leading to significant savings in execution time. A crucial point made is understanding how PostgreSQL decides on query plans and how to influence these decisions through appropriate techniques. The author also presents various optimization methods, including the use of indexes and modifications in query structure. They emphasize the importance of regularly monitoring and testing applications to adjust optimization strategies based on changing data and application requirements.
