Taking A Tour Of PostgreSQL with Jonathan Katz - Episode 42
Data Engineering Podcast
Upcoming Projects and Improvements in Postgres Version 12
Discussion on the projects and improvements planned for version 12 of Postgres, including just-in-time compiling, executor rewrite, partitioning enhancements, read and write parallelism, pluggable storage layer, SQL JSON implementation.
Summary
One of the longest running and most popular open source database projects is PostgreSQL. Because of its extensibility and a community focus on stability it has stayed relevant as the ecosystem of development environments and data requirements have changed and evolved over its lifetime. It is difficult to capture any single facet of this database in a single conversation, let alone the entire surface area, but in this episode Jonathan Katz does an admirable job of it. He explains how Postgres started and how it has grown over the years, highlights the fundamental features that make it such a popular choice for application developers, and the ongoing efforts to add the complex features needed by the demanding workloads of today’s data layer. To cap it off he reviews some of the exciting features that the community is working on building into future releases.
Preamble
- Hello and welcome to the Data Engineering Podcast, the show about modern data management
- When you’re ready to build your next pipeline you’ll need somewhere to deploy it, so check out Linode. With private networking, shared block storage, node balancers, and a 40Gbit network, all controlled by a brand new API you’ve got everything you need to run a bullet-proof data platform. Go to dataengineeringpodcast.com/linode to get a $20 credit and launch a new server in under a minute.
- Are you struggling to keep up with customer request and letting errors slip into production? Want to try some of the innovative ideas in this podcast but don’t have time? DataKitchen’s DataOps software allows your team to quickly iterate and deploy pipelines of code, models, and data sets while improving quality. Unlike a patchwork of manual operations, DataKitchen makes your team shine by providing an end to end DataOps solution with minimal programming that uses the tools you love.

Interview
- Introduction
- How did you get involved in the area of data management?
- How did you get involved in the Postgres project?
- For anyone who hasn’t used it, can you describe what PostgreSQL is?
- Where did Postgres get started and how has it evolved over the intervening years?
- What are some of the primary characteristics of Postgres that would lead someone to choose it for a given project?
- What are some cases where Postgres is the wrong choice?
- What are some of the common points of confusion for new users of PostGreSQL? (particularly if they have prior database experience)
- The recent releases of Postgres have had some fairly substantial improvements and new features. How does the community manage to balance stability and reliability against the need to add new capabilities?
- What are the aspects of Postgres that allow it to remain relevant in the current landscape of rapid evolution at the data layer?
- Are there any plans to incorporate a distributed transaction layer into the core of the project along the lines of what has been done with Citus or CockroachDB?
- What is in store for the future of Postgres?
