Hi. Creator here. I developed Perfalytics out of my frustration with analyzing Postgres performance. I've been optimizing Postgres full time for the last three years and I still find it difficult to get a good understanding of why certain queries are sometimes slow. It's clear other people have a hard time debugging Postgres performance issues based on the number of Postgres performance posts that have appeared on Hacker News over the years.[0][1][2] Perfalytics is like EXPLAIN ANALYZE on steroids. It's a Postgres extension that records the query plan of every query as it runs. By recording all this information, you're able to detect and diagnose performance issues way before you would be able to otherwise. For example, you can use this information to detect potential problems like sequential scans and on-disk sorts as soon as they start occurring. When a query suddenly becomes a lot slower, you can use Perfalytics to dig into what exactly changed between when the query was fast and when the query was slow. In addition, because Perfalytics records so much information about your queries, I'm able to make specific recommendations on how to improve of your database. This enables all teams, even those without much Postgres experience, to lean on Perfalytics to get the expertise they need to scale Postgres. If you have any questions about Perfalytics, feel free to reach out to me at michael@perfalytics.com. It's my goal to make scaling Postgres a truly painless experience.
