Get a cornucopia of resources to help you do more with your data - with a special focus on all things open source ✨ - and some of our favorite new content from TimescaleDB community members.
We’re always releasing new features, creating new documentation and tutorials, and hosting virtual sessions to help developers do amazing things with their data. And, to make it easy for our community members to discover and get the resources they need to power their projects, teams, or business with analytics, we round up our favorite new pieces in our biweekly newsletter.
We’re on a mission to teach the world about time-series data, supporting and growing communities around the world.
And, sharing educational resources as broadly as possible is one way to do just that :).

TimescaleDB tips, reading list & etc.
[TimescaleDB Tip #1]: Speed up your Grafana dashboards with
UNION ALL >>
If Grafana is slow to load your dashboards with fine-grained, non-aggregated data, you’re not alone. Use this short guide to see how to apply PostgreSQL
UNION ALL to speed up your visualizations - saving you time and CPU resources 🔥.
[TimescaleDB Tip #2]: Set up streaming replication to protect against failovers, outages and unforeseen issues >>
Check out this step-by-step tutorial to configure PostgreSQL streaming replication on your TimescaleDB instances before anything goes wrong. You’ll get guidance for synchronous and asynchronous replication and viewing diagnostics, as well as a few example scenarios.
Go back to the beginning with our first-ever blog, where we introduced the TimescaleDB beta to the world. We've come a long way in 3 years, but "boring" is even more awesome than ever — especially when it’s your database.
In this old-but-great post, we detail how traditional databases handle time-series data, why neither option is quite right, and how TimescaleDB takes a different approach. The result: a relational database with minimized memory usage, robust index support, and scale (including 15x+ INSERT rate improvements 🎉).
[Reading List]: 5 reasons why relational databases > NoSQL for IoT scenarios >>
The above blog applies to all scenarios, and, in this one, our product team focuses on why relational databases reign supreme for IoT scenarios specifically, from eliminating data silos - all of your data in one place! - to reliability and flexibility.
- 🔧 Use our IoT Simulation tutorial to test and explore how TimescaleDB handles device data.
[Time-series Fun]: Explore time-series analysis with IoT & DevOps sample datasets >>
We've created some sample datasets and example queries to get you up and running. Each scenario includes various database sizes, time intervals, and partition field values 🎉.
[Team Timescale Fun]: Last, but certainly not least, Timescale People Manager Mel continue to bring her A+ game to all things remote team bonding.
- 🐯 Want to join our tiger team? We're hiring across various departments (all roles are 100% remote and 100% awesome).
And, that concludes this month’s newsletter roundup. We’ll continue to release new content, events, and more - posting monthly updates for everyone.
