Author: . We typically talk about transactions in the context of Data Manipulation Language (DML), but the same principles apply when we talk about Data Definition Language (DDL). As databases increasingly include transactional DDL, we should stop and think about the history of transactional DDL. Transactional DDL can help with application availability by allowing you perform multiple modifications in a single operation, making software upgrades simpler. You’re less likely to find yourself dealing with a partially upgraded system that requires your database administrator (DBA) to go in and fix everything by hand, losing hours of their time and slowing your ...

Feed: Blog – ArangoDB. Author: Ingo Friepoertner. Welcome 2020! To kick off this new year, we are pleased to announce the next version of our native multi-model database. So here is ArangoDB 3.6, a release that focuses heavily on improving overall performance and adds a powerful new feature that combines the performance characteristics of a single server with the fault tolerance of clusters. If you would like to learn more about the released features in a live demo, join our Product Manager, Ingo Friepoertner, on January 22, 2020 – 10am PT/ 1pm ET/ 7pm CET for a webinar on “What’s ...

Feed: Featured Blog Posts - Data Science Central. Author: Valeria. The history of Database management systems could be interpreted as a Darwinian evolution process.The dominance of relational databases gives way to the data warehouses one, which better adapt to the earliest business intelligence requirements; then, alongside the rise of the most popular big data platforms such as Hadoop or spark, comes the era of the NoSQL databases, which were designed to privilege scalability among other features (instead of consistency for example). However, what has happened during the years, is more likely a specialization process.In fact, we are experiencing the coexistence ... Read More

Feed: Blog – ArangoDB. Author: Ingo Friepoertner. We are working on the release of ArangoDB 3.6 and today, just in time for the holiday season, we reached the milestone of RC2. You can download and take the RC2 for a spin: Community Edition and Enterprise Edition. The next version of the multi-model database will be primarily focused on major performance improvements. We have improved on many fronts of speeding up AQL and worked on things like: Subquery performance Parallel execution of AQL queries that allows to significantly reduce gathering time of data distributed over several nodes Late document materialization that ...

Feed: AWS Architecture Blog. Building on the first three parts of the AWS Lambda scaling and best practices series where you learned how to design serverless apps for massive scale, AWS Lambda’s different invocation models, and best practices for developing with AWS Lambda, we now invite you to take your serverless knowledge to the next level by reviewing the following 10 topics to deepen your serverless skills.1: API and Microservices Design With the move to microservices-based architectures, decomposing monothlic applications and de-coupling dependencies is more important than ever. Learn more about how to design and deploy your microservices with Amazon ... Read More

Author: . Recently we hosted a webinar discussing the different scaling options for databases. There are a lot of databases on the market, so it’s important to choose one that offers the scalability and consistency you’re looking for, and that’s going to vary based on the application and deployment in question. To learn more about scale up vs. scale out, eventual vs. strong consistency, and the trade offs different database solutions make to optimize scalability, please watch the webinar or read more about it in this white paper. During the webinar, we had several excellent questions that I answer in this ...

Author: mkysel. What does NuoDB do?TL;DR: NuoDB is a distributed SQL database.  NuoDB is a SQL database, it is fully transactional, fully ACID, and fully consistent. This is a stark contrast to NoSQL solutions that have emerged in the last decade. NuoDB is distributed, meaning that it is able to scale horizontally and automatically keeps multiple replicas in sync. Having multiple replicas of a database is a strict requirement for any service having 99.99% or better availability guarantees. Do you run in the cloud? NuoDB runs on all public clouds (AWS, Azure, GCP, etc.), on private clouds, and on-prem. We ... Read More
