In the summer of 2006, I was lucky enough to be an intern at Google. At the time, Google had an internal tool called gsearch that acted as if it ran grep over all the files in the Google source tree and printed the results. Of course, that implementation would be fairly slow, so what gsearch actually did was talk to a…
Today we’re open sourcing the FoundationDB Document Layer, a document-oriented database that extends the core functionality of the FoundationDB key-value store.
As a researcher/engineer (really, an algorithm developer) in the general area of audio and speech processing, I've always run into the same difficulty at all the companies I've worked at: How to quickly prototype and develop algorithms, and subsequently turn them into efficient code that can be deployed to customers.
Extensions allow Postgres to be customized and extended in powerful new ways. Here we find a tour of extensions and how they can make Postgres into much more than a relational database
CockroachDB 2.1 is 50x more scalable than Amazon Aurora at less than 2% of the price per tpmC. Read on to see performance benchmarks of CockroachDB 2.1, including the latest TPC-C results.
January 31, 2025: Post updated to clarify the reduced on-demand pricing and workloads recommendations. Just a few years ago, creating a database that could support your business at any scale while providing consistent low latency was a daunting task. That changed for me in 2012 while reading Werner Vogels’ blog post…
May 20, 2024: As of September 2022, DynamoDB now supports 100 items per transactions. March 13, 2020: Post updated to clarify how to use transactions with global tables and the increase in the maximum number of items per transaction from 10 to 25. Over the years, customers have used Amazon DynamoDB for lots of…
FoundationDB 6.0.15, our first major release since open sourcing FoundationDB in April, is now officially available!
This SEI Blog post explores the differences between statistics and machine learning and how to translate statistical models into machine learning models.
Michael Dexter returns to update his blog post on the different file systems and details some key developments that are unfolding. He covers what's being added to these respective file systems: OpenZFS, Btrfs, and bcachefs. Michael Dexter has invested his volunteer time and career in Open Source hypervisors and file…
Take a closer look into why—and where—top programming languages are popular.

A handy rule of thumb for creating a confidence interval for the probability of an event you haven't seen happen yet.
An Oracle to PostgreSQL migration in the AWS Cloud can be a complex multistage process with different technologies and skills involved, starting from the assessment stage to the cutover stage. This blog series covers the environment and configuration setups for your source Oracle database, the AWS Database Migration…
An exploration of NFL play-by-play statistics with Bokeh and Pandas.
When I got started using the Datomic database, I remember someone describing it to me as 'Event Sourcing without the hassle'. Having built Event Sourcing systems both with and without Datomic, I think this is very well put, although it might not be obvious, especially if you don't have much experience with Datomic.
Editor’s note: This tutorial illustrates how to get started forecasting time series with LSTM models. Stock market data is a great choice for this because it’s quite regular and widely available to everyone. Please don’t take this as financial advice… Continue reading Using a Keras Long Short-Term Memory (LSTM) Model…
At the heart of Meltwater’s and Fairhair.ai’s information retrieval systems lies a collection of Elasticsearch clusters containing billions of social media posts and editorial articles. The index shards in our clusters vary greatly in their access pattern, workload and size which presents some very interesting…
CockroachDB 2.1 includes a brand-new, built-from-scratch, cost-based SQL optimizer. This post explains what a cost-based SQL optimizer is, and tells the story of how we decided we really, really needed one.
Since the point of these tests is to explore the performance of the Optane SSDs, the tests are configured much like the previous ondisk benchmark, using a database approximately 5x larger than RAM, to minimize the impact of caching in RAM and force the storage devices to be exercised. However, there are some twists to…
WHAT THE RESEARCH IS: Zero-shot learning (ZSL) is a process by which a machine learns to recognize objects it has never seen before. Researchers at Facebook have developed a new, more accurate ZSL …

Update: I wrote a follow-up article about adding Loop Counters and Row Counts to SQL Plan FlameGraphs. I also show some old examples of “Bookshelf Graph” visualizations there. Check it out after reading this post first. Introduction Brendan Gregg invented and popularized a way to profile & visualize program response…
