Database Performance will at some point become important for almost every database, whether you require faster response times for your users, or your database instance is sometimes fully utilized, you will need to investigate and resolve the issue.
Performance tuning your queries is one of the best ways of increasing the speed of your database, with better performance you may even run your databases on smaller (cloud) instances.
PostgreSQL itself provides a lot of out-of-the-box tools to aid you in analyzing your performance. This session covers the following topics:
pg_stat_statementsextension to track queries
EXPLAIN ANALYZEto understand the query plan for a query
All of these topics will be accompanied with examples using the
psql terminal to
show that even though additional tools (profiling, graphing) provide a lot of value,
you do not need those tools to get started with performance improvements.
The following slides have been made available for this session:
