Feed: Blog Post – Corporate – DataStax. Author: Patrick McFadin, VP of Developer Relations. It’s hard to believe that we’re celebrating the 20th year of the Apache Software Foundation. But here we are—and it’s safe to say open source has come a long way over the last two decades. We just got back from ApacheCon, where DataStax—one of the major forces behind the powerful open source Apache Cassandra™ database—was a platinum sponsor this year.  We don’t know about you, but we couldn’t be more excited about what the future holds for software development and open source technology in particular. During ... Read More

Feed: CronJ. Author: Ayush Goel; As discussed in my last blog, there are 2 types of databases SQL and NoSQL. So in this blog, we will be looking at one type of NoSQL database that is MongoDB. MongoDB is an example of a document-type database, which means it stores data in JSON-like documents. One of the biggest reasons for its popularity is the data model used is a highly elastic one that allows us to combine and store data of multivariate types. MongoDB Architecture Let’s first discuss the architecture of MongoDB. A typical MongoDB architecture has 3 parts-  Database: A database ... Read More

Feed: CronJ. Author: Vignesh M; AI is been in our imagination for the last 40 50 years.In fact, from all the way from 2001 Space Odyssey to even like Ex Machina, there’s been a lot of movies about our fascination with AI.Unfortunately, that’s been a very negative twist around AI because ultimately all those movies are about the machines turning on humans and ultimately killing them. So I would like to offer a more optimistic outlook about AI. But it’s clear that this is something that’s really caught our imagination.The other thing that was clear was that this is all ...

Feed: Blog Post – Corporate – DataStax. Author: Sebastian Estevez. Yesterday at ApacheCon, our very own Patrick McFadin announced the public preview of an open source tool that enables developers to run their AWS DynamoDB™ workloads on Apache Cassandra. With the DataStax Proxy for DynamoDB and Cassandra, developers can run DynamoDB workloads outside of AWS (including on premises, in other clouds, and in hybrid configurations). The Big Picture The cloud has changed computing forever, and as cloud services continue to evolve up the stack, the new capabilities they offer developers come with trade-offs. One of the trade-offs developers, architects, and ... Read More

Feed: Blog Post – Corporate – DataStax. Author: Louise Westoby, Senior Director, Product Marketing. Historically, software was monolithic. In most cases, development teams would have to rewrite or rebuild an entire application to fix a bug or add a new feature. Building applications with any sense of speed or agility was largely out of the question, which is why software suites like Microsoft Office were generally released once a year. Much has changed over the last decade or so. In the age of lightning-fast networks and instant gratification, leading software development teams are adopting DevOps workflows and prioritizing CI/CD so ... Read More

Feed: Neo4j Graph Database Platform. Author: Jocelyn Hoppa. Almost a decade ago, Neo4j took off as a transactional graph database management platform. Just a year after its initial launch, a new, powerful query language called Cypher was introduced to allow expressive, efficient querying and other interactions with the graph data in Neo4j. Today, Neo4j supports graph analytics including implementation of a wide variety of state-of-the-art graph algorithms with custom optimizations for Neo4j’s graph database model. It achieves unmatched performance in scalability, routinely running millions or even billions of nodes and edges.The next natural step for the platform in 2019 is ... Read More
