DELETEs Are Difficult
Deep dive into SQL & PostgreSQL to build reliable, rock-solid solutions with tips and tricks that keep business online. Data is everything. Explore, learn and innnovate to get them where you need faster and more efficiently.
While the AUTOVACUUM might sounds as a bad news, without it, your database would quickly become bloated with dead tuples, leading to degraded performance, slower queries, increased storage usage, and even the potential for out-of-disk errors as unused space cannot be reclaimed. By batching, you give PostgreSQL more breathing room to manage changes without overwhelming regular transactional workloads - unless, of course, you’ve scheduled dedicated maintenance time for the operation. By considering DELETE operations during schema design, you can maintain an efficient database, reduce maintenance headaches, and ensure it continues to run smoothly as your data grows.
