Timescale Newsletter Roundup: July 2022

Timescale Newsletter Roundup: July 2022

Welcome to our July newsletter roundup! We had a lot going on this month—join us along for the ride. First, we share the results of our worldwide survey on the PostgreSQL community: the State of PostgreSQL report is back for the third year to share how PostgreSQL users work, the tools they use, and what are their thoughts on the community.

Second, learn how to do better and faster aggregation on PostgreSQL and how to write truly efficient queries for time-series analysis, courtesy of our #AlwaysBeLaunching week.

And third, check out our resources on SQL, PostgreSQL, observability, and much more. There's a bit of everything for everyone, from views and materialized views in PostgreSQL (a lengthy and incredibly detailed explanation by Timescale's own David Kohn) to Observability and metrics, as we round off a series of three blog posts with an article that compares Prometheus and OpenTelemetry metrics.

Enjoy! See you next month!

State of PostgreSQL 2022

The State of PostgreSQL 2022 results are in! Our goal was to learn more about how people around the world use PostgreSQL—and we hope you find the results as interesting as we do. Thank you to everyone who took the time to share your experience with PostgreSQL. 🙏

[Read] How PostgreSQL Views and Materialized Views Work and How They Influenced Continuous Aggregates’ Design in TimescaleDB >> Continuous aggregates are one of TimescaleDB’s most popular features. Still, it’s challenging to fully understand them without some context on PostgreSQL views and materialized views. In this blog post, we fill that gap and tell you the story of how views and materialized views shaped the design of this feature.

[Read] Prometheus vs. OpenTelemetry Metrics: A Complete Guide >> Prometheus or OpenTelemetry? As you monitor your systems, we believe this is a choice you will have to make sooner or later, which is why we rounded off our three-part series on metrics by explaining the differences, similarities, and integration between the metrics in both systems.

📒 Read our metrics series' first two blog posts: deep dive into the four types of Prometheus metrics, and then examine how metrics work in OpenTelemetry.
