Recently, a Facebook dataset was released consisting of the complete set of users from the Facebook networks at 100 American institutions, and all of the in-network “friendship” links between those…
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.
Install TimescaleDB on Linux, macOS, Windows, Docker, Kubernetes, or from source
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…
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…
More than a billion people now use Facebook Messenger to instantly share text, photos, video, and more. As we have evolved the product and added new functionality, the underlying technologies that …
EnclaveDB: A secure database using SGX Priebe et al., IEEE Security & Privacy 2018 This is a really interesting paper (if you’re into this kind of thing I guess!) bringing together the security…
Spotify's direct listing IPO filing reveals how monthly churn fell from 7.7% to 5.5% as personalization and family plans drove subscriber retention at scale.
Recently I was working on a project where I have to cluster all the words which have a similar name. For a novice it looks a pretty simple job of using some Fuzzy string matching tools and get this done. However in reality this was a challenge because of multiple reasons starting from pre-processing of the data to…
Now that MySQL 8 and PostgreSQL 10 are out, it's a good time to revisit how the two major open source relational databases compete against each other. Before these versions, the general perception has been that while Postgres is superior in feature sets and its pedigree, MySQL is more battle
Recent media coverage of Onavo Protect encouraged me to investigate the code for the iOS version of their app. I wanted to determine what…
Take a closer look into why—and where—top programming languages are popular.
If you’ve had the chance to read our GDPR white paper or our previous GDPR primer blog post, you’ve, no doubt, seen the word "pseudonymization" used extensively to describe one technical measure that ...
An important feature of transactional databases like SQLite is "atomic commit". Atomic commit means that either all database changes within a single transaction occur or none of them occur. With atomic commit, it is as if many different writes to different sections of the database file occur instantaneously and…
One of our large scale data infrastructure challenges here at Cloudflare is around providing HTTP traffic analytics to our customers. HTTP Analytics is available to all our customers via two options:
Back in the early 1980s, Dr. David DeWitt – who you might know from past PASS Summit keynotes, formerly of Microsoft (LinkedIn) – was working on measuring database performance. His team wrote a benchmark, ran it against Oracle, and Oracle didn’t fare well in the results. Oracle reacted as one would expect – they were…
Household income determines health spending, mostly via higher intensity, not prices. US behaviors are consistent with well-measured income in multiple dimensions.
