PlanetScale Postgres Scalability Guide

TL;DR

A technical deep dive explaining why massive DELETE operations kill Postgres performance and why partitioning is your only real escape from table bloat.

Who is this actually for?

Backend engineers and DBAs managing high-traffic Postgres instances who are tired of fighting autovacuum and slow queries.

The Good

• Provides a realistic look at how MVCC overhead makes large-scale deletes a nightmare.
• Advocates for partitioning, which is the only sane way to handle multi-terabyte datasets without locking up your production DB.

The Catch (Potential Downsides)

Refactoring an existing monolithic table into partitions is a massive headache that requires careful migration planning. Also, remember this is high-quality content marketing meant to get you into the PlanetScale ecosystem.
