Acid transactions, ACID properties, and the CAP theorem are two important concepts in data management and distributed systems. It’s unfortunate that in both acronyms the “C” stands for “Consistency,” but actually means completely different things. What follows is a primer on the two concepts and an explanation of the differences between the two “C”s. What […]
The New Year brings about the perfect time to start fresh and set some new goals. So, in the spirit of things, we’ve laid out a few New Year’s resolutions that all database professionals can take into account as they look to turn over a new leaf in 2018 and build on their successes. Create […]
Upwards of 50% of Volt Active Data customers deploy in public and private clouds, so we get queries regularly on how to set up interfaces for cloud instances. One question that’s come up a few times is, ‘How do I configure Volt Active Data to be secure but still allow me to monitor through the […]
Real-time connectivity will stop being an optional way to incrementally improve efficiency and instead become a baseline requirement without which things simply won’t work. Over the next decade the ratio of humans to computers on the internet will change radically. We’re moving from an era where interactions were mostly between individual humans and servers to […]
Let me start by making an arrogant statement: There is no such thing as eventual consistency. There is only ‘Immediate Consistency’ and ‘Wrong’. A lot of people would regard me as being unreasonable, but from my perspective I have a chain of reasoning that I don’t think you can fault: The purpose of any database […]
This post is a contribution from Cheryl Wiebe, Partner of Advanced Analytics at Teradata West Region. If you follow Gartner, Forrester and other industry analysts, you’re probably a reader of Gartner’s ‘Hype Cycles’ and Forrester’s ‘Waves’. According to Gartner, IoT is at the top of the Hype Cycle, and is forecast to deliver economic value […]
Working on distributed systems is fun, but not easy! As a software engineer at Volt Active Data, a big chunk of my time is spent testing software on a cluster of machines as part of new feature development and also for customer issue reproduction. Any software engineer who does this on a daily basis knows […]
There has been another round of online conversations about the CAP theorem as the internet community continues to discuss its implications on networked databases. Coda Hale recently wrote a well received article titled CAP paper by Gilbert and Lynch. Scattered in the larger conversation is a continued mis-perception of my position regarding the CAP theorem.
