In 2016, we partnered with Research Now to conduct a survey on a subject we take very seriously: data consistency. The results were shocking. While there was wide agreement on what is defined by “critical data” (financial data), only 58% of people surveyed stated that...
We did a survey last year to see how enterprises viewed the need for “real time” (see https://www.voltdb.com/blog/worlds-apart-real-time-data-disconnect). Since we are leaders in the fast data space, we wanted to try to gauge where companies were on the real-time maturity curve. The results were interesting, which...
Billions and billions[1] of transactions are executed each and every day by production-deployed VoltDB applications.A back-of-the-napkin calculation puts the number north of 50 billion a day. The number is likely much, much higher. These billions of transactions are executed across a variety of innovative applications,...
We get a lot of questions about what VoltDB is, what it does well, and how it can help enterprises solve a range of data management challenges. This post will address a few of those questions. We'll have more posts like this, so check back often. How...
There’s a very simple distinction in the database world that tends to be ignored. Your database either:Defines the WorldOr, itReacts to the WorldIf your database ‘Defines the World’ it means that if it doesn’t happen in the database, it doesn’t happen at all....
In my previous post, I described four applications (three implemented, one an example) that require, or at least strongly benefit from, strong ACID transactions. With that out of the way, we can now get to the fun bits. Today’s claim: most databases that claim to be...
There’s a lot of discussion about the value of consistency and ACID transactions in data management. I thought it would be useful to describe three fully implemented enterprise-class applications, and one example application, that need ACID transactions. These descriptions should make an abstract concept a...
VoltDB is already the go-to product for developing fast data applications because of its unparalleled performance, availability, and durability. v6.0 builds on that foundation by extending existing capabilities and simplifying the development process.What does a VoltDB application look like? Some of the characteristics are:Applications...
The 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...
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...
