Feed: Redis Labs. Author: Kyle Davis. The Helicoprion is a now extinct but strange animal that roamed the seas of the early Permian. It looks more or less similar in both size and shape to a contemporary Great White Shark. Most likely, it was a formidable predatory of the seas. The thing that set it apart was that it had a “Tooth-whorl,” which is somewhat akin to having a shark teeth circular saw located inside the lower jaw. Seems like it would be a good idea, but evolution had a different idea and we don’t have any existent animals like ... Read More

Feed: Redis Labs. Author: Loris Cro. Let’s talk about communication tools and patterns. With the introduction of Streams in Redis, we now have another communication pattern to consider in addition to Redis Pub/Sub and other tools like Kafka and RabbitMQ. In this article, I will guide you through the defining characteristics of various communication patterns, and I’ll briefly introduce the most popular tools used to implement each. Finally, I’ll leave you with a small take-away that will hopefully help you build better solutions faster. Synchronous Communication In this context, synchronous means that all parties need to be active at the ... Read More

Feed: Redis Labs. Author: Madhukar Kumar. Last week, we released RedisGraph 1.2.0. If you’ve been using RedisGraph or considering trying out the module, this is a good time to see what we’ve been up to as we continue to enhance its graph processing capabilities. Let’s review some of the more notable additions in the new release: Multiple edges of the same type Up until this release, connecting node A to node B via an edge of type R and then forming another connection of the same type between the two was not possible. as the latter would overwrite the former ...

Feed: Redis Labs. Author: Preston Reyes. At RedisConf19, I demoed a solution for running full-text RediSearch over nodes in RedisGraph. The days leading up to the event are a bit of a fog, but now, a few weeks later, I realized we should explain more about how we did this and release the source code. In this demo, I showed a little interface that allows you to search for animals and see how they are related via the biological classification system (kingdom, phylum, class, order and so on). The full-text portion was based on the first English paragraph from wikipedia ... Read More

Feed: Redis Labs. Author: Preston Reyes. When I started out building websites, I didn’t focus much on performance. Performance is a luxury you worry about once you’ve mastered the basics, like HTML and CSS or whatever programming language you’re using on the backend. A beginner’s goal is to stand a site up, be able to get from page-to-page and make sure it looks good on a bunch of devices. Caching and performance are things we figure out later. There are many great reasons to look into caching solutions. From an SEO perspective, Google penalizes slow websites. If your site has ... Read More

Feed: Redis Labs. Author: Preston Reyes. Recently, I was chatting with one of my friends who manages data warehousing solutions at a retail company. He posed an interesting problem: “We have a pain point with our data warehousing solutions. We have use cases where we need to record data and perform analytical operations in real time. However, sometimes it takes minutes to get the results. Can Redis help here? Keep in mind, we cannot rip and replace our SQL-based solution all at once. We can only take a baby step at a time.” If you are in the same situation ... Read More

Feed: Redis Labs. Author: Preston Reyes. Redis Day New York is fast approaching (June 27th – get your tickets NOW). This will be a new event for New York, but not a new event for us. We’ve done it three times in Tel Aviv, once in London and now we’re adding New York. The Redis Day format is fairly unique and very different from RedisConf. At RedisDay, we have a single track, short talks and (generally) we don’t have a public Q&A time per session. What does that mean? A few things: You don’t have to worry about people not ...

Feed: Redis Labs. Author: Preston Reyes. Yesterday, I wrote about how Redis can benefit distributed development teams by helping them release new features safely and roll them back with minimal impact when required. Today, I’ll dive into specific details about how feature toggles, feature context and error logs can enhance your continuous integration and continuous deployment (CI/CD) process. Feature Toggling with Redis “Feature toggling” is a set of patterns that help you deliver new functionality to application users rapidly but safely. Feature toggles are also referred to as feature flags, feature bits or feature flippers. Figure 5: Feature toggles stored ... Read More

Feed: Redis Labs. Author: Preston Reyes. In an effort to run, run, run… you don’t want to make the $460 million dollar mistake that Knights Capital made back in 2012. This single-day computer system failure of a leading financial market-maker offers several lessons for the broader IT community, including the critical importance of your system components’ design, implementation and DevOps details. In this two-part blog, I’ll share some ideas to help development teams keep their continuous integration and continuous deployment (CI/CD) processes fool-proof. In particular, I’ll show how you can manage continuous updates by using feature toggles and feature context ... Read More

Feed: Redis Labs. Author: Keren Ouaknine. Background RediSearch is a distributed full-text search and aggregation engine on the top of Redis, allows users to execute complex search queries on their Redis dataset in an extremely fast manner. The unique architecture of RediSearch (implemented as a Redis module, written in C and built from the ground up on modern and optimized data-structures) allows it to be a true alternative to other search engines in the market when using it as a stand alone search engine for indexing and retrieval searchable data.When we first launched RediSearch we benchmarked it against popular search ...
