PostgreSQL 9.6 was released a few days ago and it’s another huge milestone for the PostgreSQL community ! The release notes are way too long, so I’ve decided to pick up 6 big improvements that may change the way you will use PostgreSQL.
The following is an update on the security vulnerability identified in December 2025.
dbt Labs has acquired SDF Labs to enhance analytics engineering solutions. Learn how this partnership strengthens the modern data stack.
Our latest ANN release supports scales of 100+ billion vectors in a single search index, with 200ms p99 query latency at 1k QPS and 92% recall.
Things a programmer coming from another language needs to know about R, especially those things that might be most surprising
Safely leverage PostgreSQL's asynchronous commit for significant performance gains
Index creation time is a critical database metric. Learn more about how Lantern enables 90x faster index creation times than pgvector, and how Lantern compares to Pinecone.

Dataflow is a fully managed streaming analytics service that reduces latency, processing time, cost through autoscaling and real-time data processing.
(This post is coauthored by Alexander Thomson and Daniel Abadi ) It is a poorly kept secret that NoSQL is not really about eliminating SQL ...
At my company we use a small SQLite database. We define the schema in a single file with SQL CREATE TABLE statements. If we add tables, columns, or indexes, our application will create them automatically the next time it starts up.
What in the world is Explorative Modeling?
Turso is becoming the LLVM of databases: one modern, reliable Rust core with many SQL frontends. After rewriting SQLite, we are now building Postgres.
Common Crawl aims to change the big data game with our repository of over 40 terabytes of high-quality web crawl information into the Amazon cloud, the net total of 5 billion crawled pages.
Efficient SQL data transformations & real-time analytics with dbt + Materialize: a powerful operational data warehouse combo.
In my work I’ve developed a mental framework related to data modeling, which has helped greatly both when coming up with a model and when making decisions down the road about how to use that model. Here I will establish three different categories of data in software: Constants, State, and Cached Values. By “data” I…
My previous Let’s Make a Map tutorial describes how to make a basic map with D3 and TopoJSON ; now it’s time to cover thematic mapping in the form of a proportional symbol map. The simplest symbol is a circle, or bubble , whose area is proportional to the associated data. In this tutorial, we’ll make a bubble map of…
This is another experiment in visualizing 24-hour cyclical data. My last post explored a method of linear representation (the Double Time Bar Chart). Linear representations have problems when it comes to showing the cyclical nature of time data (ie there is no start or end of a 24 hour cycle). Inspiration When trying…
The virtual machine? Yep, but not the Java Virtual Machine.
Window functions in PostgreSQL are valuable when you want to compare & contrast data between rows. And window functions are key in analytics use cases. This post covers the basic structure of window functions as well as some of the more interesting things you can do with them.
We love data, big and small and we are always on the lookout for interesting datasets. Over the last two years, the BigML team has compiled a long list of sources of data that anyone can use. It…
