Feed: Redis Labs. Author: Kyle Davis. E-mail marketing is an effective way to reach customers, but it comes with a variety of challenges that can be difficult to overcome. The nature of email is static after delivery: once the message has left your e-mail server, you have very little control — or do you? Let’s take a look at a technique that can provide some level of dynamic control after you send your e-mail. Imagine you’re sending out an email with three deals. You’re not sure which deals will perform the best. After the email is sent, you’ll have a very clear ... Read More

Feed: Redis Labs. Author: Roshan Kumar. Imagine visiting an amusement park, consuming large quantities of all four primary amusement park food groups (which are corn dogs, funnel cake, snow cones, and cotton candy of course), and then spinning around wildly on the Tilt-A-Whirl. The volume and variety (and dare we suggest velocity?) of food you’ve just consumed is likely to overwhelm your stomach, causing discomfort and forcing it to slow down and regroup in order to accommodate the day’s indulgences. But your software stack isn’t allowed the luxury of slowing, not even a fraction of a sub-millisecond; it needs to ... Read More

Feed: Redis Labs. Author: Tague Griffith. This post is part five of a series of posts examining the features of the Redis-ML module.  The first post in the series can be found here.  The sample code included in this post requires several Python libraries and a Redis instance with the Redis-ML module loaded.  Detailed setup instructions for the runtime environment are provided in both part one and part two of the series. Decision Trees Decision trees are a predictive model used for classification and regression problems in machine learning.  Decision trees model a sequence of rules as a binary tree ... Read More

Feed: Redis Labs. Author: Cihan B. Very excited to announce that we are launching a preview program for our upcoming release of Redis Enterprise Pack version 5.0. As part of the program, we will give you a chance to directly provide feedback on the new capabilities and be part of the inner circle with engineering teams that deliver Redis open source bits and Redis Enterprise services and products. 5.0 is a huge release with improved high availability, better scaling performance for Redis applications, advanced security and real-time search + query with indexing at Redis speeds. Here are the highlights; Geo-distributed, Active-Active Redis Applications with CRDBs ... Read More

Feed: Redis Labs. Author: Tague Griffith. This post is part four of a series of posts introducing the Redis-ML module.  The first article in the series can be found here.   In this post, we’re going to look at the matrix operations provided by the Redis-ML module and show some examples of how to process Matrix data using the Redis database. Technical Requirements The example code in this post is written in Python and requires a Redis instance running Redis-ML.  The instructions for setting up Redis can be found in either part one or part two of this series.   ...

This post is part three of a series of posts introducing the Redis-ML module.  The first article in the series can be found here.  The sample code for this post requires several Python libraries and a Redis instance running Redis-ML.  Detailed setup instructions to run the code can be found in either part one or part two of the series. Logistic Regression Logistic regression is another linear model for building predictive models from observed data.  Unlike linear regression, which is used to predict a value, logistic regression is used to predict binary values (pass/fail, ...

Feed: Redis Labs. Author: Kyle Davis. We’ve been busy working on some video walk-throughs of common situations with Redis Enterprise. In the first video, we talk about how to replicate between different clusters. This feature is useful in several circumstances: recovering from a disaster, speeding up read performance, geo-located databases, and making duplicates for testing or reporting. This can be done entirely from the Redis Enterprise UI and is a short point-and-click operation. Honestly, it’s pretty neat to see replication between clusters occur so seamlessly. In the second video, we go over some setup techniques to achieve high availability. What’s interesting ... Read More

Feed: Redis Labs. Author: David Maier. This article was originally posted on nosqlgeek.org If you follow my news on Twitter then you might have realized that I just started to work more with Redis.  Redis (=Remote Dictionary Server) is known as a Data Structure Store. This means that we can not just deal with Key-Value Pairs (called Strings in Redis) but in addition with data structures as Hashes (Hash-Maps), Lists, Sets or Sorted Sets. Further details about data structures can be found here: Indexing in Key-Value Stores With a pure Key-Value Store, you would typically maintain your index structures manually ... Read More

Feed: Redis Labs. Author: Tague Griffith. This post is part two of a series of posts introducing the Redis-ML module. In the previous post of the series, we used the Python scikit-learn package and Redis to build a system that predicts the median house price in the Boston area.  Using linear regression, a powerful tool from statistics, we constructed a pricing model that predicted the median home price for a neighborhood using the average number of rooms in a house. At the end of the post we said that the next post would cover classification, a machine learning process of ... Read More

Feed: Redis Labs. Author: Keren Ouaknine. Overview Our partners/friends at Intel have recently announced the availability of Optane, an NVMe-based SSD device built on top of the new persistent memory technology from Intel and Micron, 3D XPoint (3DXP). Intel Optane Technology    One of the main advantages of 3DXP is that it gives the application a way to decide which part of the dataset should be stored on fast memory, e.g. DRAM, and which part on a slower memory, e.g. Flash/Nand. Our Redis Enterprise Flash (RF) product was built from the ground-up with the same approach in mind.We therefore decided ... Read More
