It’s Not You, It’s Me: "Breaking Up" With Massive Tables via Partitioning
Details
Similar to memory configurations and Active-Active, when you find yourself Googling "How to partition a Postgres table", you're usually in a tight spot. However, although real-life use cases for partitioning typically start with a large, production table where uptime is critical, most documentation and blogs only cover setting up new partitioned tables -- ignoring the delicate work necessary to migrate safely with minimal downtime.
This talk actionably addresses that knowledge gap: covering multiple ways to partition large, production tables.
This talk will discuss:
- Basic Postgres partitioning internals
- Choosing between partitioning strategies (with examples)
- Rules of thumb, and when NOT to partition
- Methods of migrating a live, production table to a partitioned table (with examples and demo code)
- Partitioning observability and maintenance
Pizza is provided, and we also have a user group lending library of books & papers related to PostgreSQL and Databases.
