Adding a Search Engine to Redis: Adventures in Module-Land

TL;DR: We’ve utilized the powerful Redis Modules API to build a super-fast and feature-rich search engine inside Redis, from scratch — with its own custom data types and algorithms. Earlier this year, Salvatore Sanfilippo, the author of Redis, started developing a way for developers to extend Redis with new capabilities: the Redis Modules API. This API allows users to write code that adds new commands and data types to Redis, in native C. At Redis …

Redis Recommends…

You just finished watching Narcos, season 2 and are about to slip into the post-binge-watching doldrums, when up pops a recommendation from Netflix. “Because you liked Narcos, you should watch..El Patron De Mal.” Its not just Netflix. The New York Times does it, Amazon does it, Google does it, even your teenager’s school’s application has recommendations. Applications are getting smarter every day and it is no secret that they rely on extremely smart developers and …

All Substance and Plenty of Deserved Hype Too

In the past 12 months, Redis Labs has celebrated some impressive market leadership milestones—and we have every reason to believe the party’s just getting started. In July, we announced a 350% year over year revenue growth for our Redis Labs Enterprise Cluster (RLEC) and an expansion to more than 55,000 accounts for our Redis Cloud offering—enough to make us the fastest growing NoSQL provider in the marketplace. On August 25th, we announced that Redis Labs’ …

Count Min Sketch: The Art and Science of Estimating Stuff

This post is about what are, in my opinion, two of the most exciting things in the world: probabilistic data structures and Redis modules. If you’ve heard about one or the other then you can surely relate to my enthusiasm, but in case you want to catch up on the coolest stuff on earth just continue reading. I’ll start with this statement: large-scale low-latency data processing is challenging. The volumes and velocities of data involved …

Springing Into Action: Pivotal and Redis Labs at SpringOne Platform 2016

My delayed Southwest flight from San Jose to Las Vegas gave me some extra time to finalize my game plan for attending SpringOne Platform 2016. I was really excited for the trip, and the delay (followed by another delay) did little to dampen my excitement. Upon landing in Vegas, I was greeted by the instantly sweat-inducing 112 degree heat/humidity, as well as the usual long weaving taxi line comprised of every demographic imaginable. The good …

Writing Redis Modules

I’ve been using Redis for about six years now, and over the years I’ve exploited its few data types to do some pretty versatile things such as geographical queries, text search, machine learning and more. But over the years, I can’t even count the number of times I’ve found myself (as did many other users) wishing that Redis would have this or other data structure, command or capability it is lacking. Not having them forced …

Hyper Growth, INITIATED!

By one recent estimate, the NoSQL database market is on track to achieve a growth rate of 21% CAGR through 2020. The outlook is even rosier for the global Database-as-a-Service (DBaaS) market, which is expected to grow at a CAGR of more than 65% in the same time period. As the most innovative player in the NoSQL database market and the NoSQL pioneer to offer DBaaS, Redis Labs is perfectly poised to ride both of …

Why Redis Labs’ Modules are AGPL

Redis Labs’ Modules are released under the GNU Affero General Public License​ (AGPL)​. This Free Software Foundation license is fairly new, and thus I wanted to ​explain why we chose this license. Our goal with using AGPL is to ​add the concept of copyleft ​for ​enhanced Redis functionality. The core Redis Open Source Project is based on the three clause BSD license, which allows unlimited redistribution for any purpose as long as its’ copyright notices …

Money! Money! Money! – How to Save it Good!

Avnet rolls out IBM’s RapidBuild Program with Redis Labs! Redis, as we know, is the world’s most popular in-memory NoSQL and rapidly becoming a default ingredient of most modern application stacks. Modern application architects use it to help their applications scale to humungous volumes of traffic at sub-millisecond latencies –with very little hardware. This blog is about saving even more money with IBM’s RapidBuild Program for POWER8 systems. Today, Avnet announced that it is the …

February 8th outage – post-mortem

On Monday February 8th 2016, at 17:45 UTC, we experienced a major outage in one of the Google Cloud Platform clusters that we employ in providing the Redis Cloud service. By 19:30 UTC we were able to bring the service back to over 95% of affected users, and had it completely recovered by 20:38 UTC. [.. ] Due to this outage, despite it being the first of kind for us, we've taken immediate steps to ensure that such incidents do not recur.

Connecting Spark and Redis: A Detailed Look

"I wanted to make sure that the results were stored so I could use them in later computations. Redis' Sorted Sets are a perfect match for the word-count pairs and would also allow me to query the data like I'm used to. It took only one line of Scala code to do that."

ZeroBrane Studio Plugin for Redis Lua Scripts

Just before Christmas, Salvatore Sanfilippo published the first release candidate for Redis v3.2. The upcoming v3.2 delivers new features (such as geo spatial indexes and cluster rebalancing) and many great improvements (including Matt Stancliff's Quick Lists and Oran Agra's SDS and Jemalloc optimizations). For this post, I'll focus on just one of these – the Redis Lua Debugger (LDB) – and also share a New Year's present from Redis Labs (spoiler). LDB is a mode …

3 Critical Points about Security

Over the recent weeks there's been an increase in the number of reports about NoSQL breaches in general, but also specifically in those relating to Redis. The latter is, in all likelihood, the aftermath of Salvatore Sanfilippo's blog post "A few things about Redis security." That particular post was only the spark that lit the fire – I'd argue that the seeds for the breaches were laid in the ground long ago. And they're still …

How Redis is Used in Practice

In a recent eye opening survey of 116 redis users, we at Redis Labs were pleasantly surprised by the enormous breadth and depth of Redis usage. 71% of respondents were planning to increase their usage of Redis as their data, applications and users scaled up. Some of our other favorite data points were: 1 Top applications using Redis spanned Analytics, Mobile, Social, Retail, Financial, Gaming – and in addition to these – there was an …

Salvatore Sanfilippo – Welcome to Redis Labs

I usually begin this type of post with a variation on the sentence "Today I am delighted to…" Today, however, these words aren’t filler — they truly are the best way to express that I am delighted to welcome Antirez (a.k.a Salvatore Sanfilippo), Redis' creator, to Redis Labs. You can read more about this development on Antirez's blog and in our press release, but here's another perspective – mine. I'm a Redis geek and if …
