Developers who build Worker applications focus on what they're creating, not the infrastructure required, and benefit from the global reach of Cloudflare's network. Many applications require persistent data, from personal projects to business-critical workloads. Workers offer various database and storage options tailored to developer needs, such as key-value and object storage. Relational database

Parquet and Postgres in the Data Lake | Crunchy Data Blog
Interested in Spatial analytics? You can now connect Postgres and PostGIS to CSV, JSON, Parquet / GeoParquet, Iceberg, and more with Crunchy Data Warehouse. Static Data is DifferentA couple weeks ago, I came across a blog from Retool on their experience migrating a 4TB database.

In 2006 Microsoft conducted a customer survey to find what new features users want in new versions of Microsoft Office. To their surprise, more than 90% of what users asked for already existed, they just didn't know about it. To address the "discoverability" issue, they came up with the "Ribbon UI" that we know from Microsoft Office products today. Office is not unique in this sense. Most of us ar

I see a lot of bad system design advice. One classic is the LinkedIn-optimized “bet you never heard of queues” style of post, presumably aimed at people who are new to the industry. Another is the Twitter-optimized “you’re a terrible engineer if you ever store booleans in a database” clever trick1. Even good system design advice can be kind of bad. I love Designing Data-Intensive Applications, but
Adopting Wide Event-style instrumentation has been one of the highest-leverage changes I've made in my engineering career. The feedback loop on all my changes tightened and debugging systems became so much easier. Systems that were scary to work on suddenly seemed a lot more manageable. Lately there have been a lot of good blog posts on what "Wide Events" mean and why they are important. Here are
Database Fundamentals
About a year ago, I tried thinking which database I should choose for my next project, and came to the realization that I don't really know the differences of databases enough. I went to different database websites and saw mostly marketing and words I don't understand. This is when I decided to read the excellent books Database Internals by Alex Petrov and Designing Data-Intensive Applications by

Introduction to Go 1.23 The latest Go release, version 1.23, arrives six months after Go 1.22. Most of its changes are in the implementation of the toolchain, runtime, and libraries. As always, the release maintains the Go 1 promise of compatibility. We expect almost all Go programs to continue to compile and run as before. Changes to the language The “range” clause in a “for-range” loop now accep
Ever wanted more different ways to understand what’s going on in a program? Here I catalogue a huge variety of tracing methods you can use for varying types of problems. Tracing has been such a long-standing interest (and job) of mine that some of these will novel and interesting to anyone who reads this. I’ll guarantee it by including 2 novel tracing tools I’ve made and haven’t shared before (loo
Pandas is a very popular tool for data analysis. It comes built-in with many useful features, it's battle tested and widely accepted. However, pandas is not always the best tool for the job. SQL databases have been around since the 1970s. Some of the smartest people in the world worked on making it easy to slice, dice, fetch and manipulate data quickly and efficiently. SQL databases have come such
