Feed: Redis Labs. Author: Chris Cheung. Here’s a brief introduction to Red Hat OpenShift, including questions we often get asked and our thoughts on why it’s a great choice for deploying and running your Redis Enterprise Cluster. What is OpenShift? There are a few pieces of background you should have before I can properly answer that question, so let me start with a simple definition and then progressively fill in the details. OpenShift is Red Hat’s Platform-as-a-Service (PaaS) offering for running containerized applications based on their Kubernetes distribution. What is a Platform-as-a-Service (PaaS)? PaaS is a category of cloud computing ... Read More

Feed: Redis Labs. Author: Chris Cheung. Successful applications tend to become complex over time. A microservices architecture offers the ability to decompose your app into many loosely-coupled services organized around business capabilities, thereby alleviating some of the complexities. Of course, microservices are not a free lunch, but for most large, complex apps, they allow teams to deploy new features faster, scale more easily, and pick the best technology stacks. But what about distributed data? Each microservice is able to select the right database for the right job by employing a data model based on key-value, graph, hierarchical, JSON, streams, search, and ... Read More

Feed: Redis Labs. Author: Chris Cheung. Here are five things to keep in mind when writing a Redis module. While this list is non-exhaustive, my aim is to offer a good way to get started if you don’t yet have much experience with module building. 1. Find a compelling module use case Redis already has plenty of tools that allow you to build the exact solution you need. One example could be locks. Using SET with the NX option, you can create a lock key, and by combining it with EXPIRE, you get a lock lease. This can be very ... Read More

Feed: Redis Labs. Author: Chris Cheung. At RedisConf19, we officially released a new module called RedisGears. You may have already seen some other modules by either Redis Labs or the community at large, but Gears will defy any expectations you have. It really pushes the limits of what is possible with modules. Gears scripts At first glance, RedisGears looks like a general-purpose scripting language that can be used to query your data in Redis. Imagine having a few hashmaps in your Redis database with user-related information such as age and first/last name. Here is the execution breakdown for the RedisGears ... Read More

Feed: Redis Labs. Author: Ariel Shtul. Background You may find yourself wondering whether you should use more probabilistic data structures in your code. The answer is, as always, it depends. If your data set is relatively small and you have the required memory available, keeping another copy of the data in an index might make sense. You’ll maintain 100% accuracy and get a fast execution time. However, when the data set becomes sizeable, your current solution will soon turn into a slow memory hog as it stores an additional copy of the items or items’ identifiers. Therefore, when you deal ... Read More

Feed: Redis Labs. Author: Pieter Cailliau. Today we are happy to announce the general availability (GA) of RedisTimeSeries v1.0. RedisTimeSeries is a Redis module developed by Redis Labs to enhance your experience managing time series data with Redis. We released RedisTimeSeries in preview/beta mode over six months ago, and appreciate all the great feedback and suggestions we received from the community and our customers as we worked together on this first GA version. To mark this release, we performed a benchmark, which achieved 125K queries per second with RedisTimeSeries as compared to other time series approaches in Redis. Skip ahead ... Read More

Feed: Redis Labs. Author: Nail Sirazitdinov. All modern consumer applications must scale easily and cost-efficiently, and for this, linear database performance is key. With our shared-nothing architecture, we’ve proven again and again that a single Redis Enterprise cluster can scale infinitely in a linear manner by simply adding shards and nodes. But that doesn’t mean we’re resting on our laurels. At RedisConf18 we demonstrated that a single Redis Enterprise cluster could reach 50 million operations per second (ops/sec) with only 26 AWS instances while keeping latency under 1 millisecond, and today we’re pleased to share that Redis Enterprise has set ...

Feed: Redis Labs. Author: Chris Cheung. In my previous post, I gave a high-level overview of our Redis-based, industrial Internet of Things (IoT) technology at Inovonics, which is the leader in wireless networks. I will give more details on each of our system components in this and subsequent posts, and introduce you to some of the more technical features of Redis (and Redis Enterprise in particular) that we use at Inovonics. To recap my previous post, the following components comprise a full IoT system: Sensors (also known as “end points” or collectively referred to as the “edge”): Devices used to ... Read More

Feed: Redis Labs. Author: Chris Cheung. Data is the foundation of all digital transformation initiatives in finance, and Redis Enterprise is the industry’s high-performance database of choice. This enterprise edition of Redis simplifies the development of highly performant, reliable and seamlessly scalable real-time applications, including mobile, social, personalization, internet of things (IoT), fraud mitigation and many other solutions. The popularity of NoSQL databases According to Forrester, half of global data and analytics technology decision makers either have implemented or are implementing flexible NoSQL platforms, like Redis Enterprise. NoSQL databases are critical for a new generation of financial applications built with ... Read More
