Redis Loadable Modules System - <antirez>
antirez 3102 days ago. 264402 views. It was a matter of time but it eventually happened. In the Redis 1.0 release notes, 7 years ago, I mentioned that one of the interesting features for the future was “loadable modulesâ€. I was really interested in such a feature back then, but over the years I became more and more skeptic about the idea of adding loadable modules in Redis. And probably for good r

Running Redis in production |
2014-11-11 00:00:00 -0800 Overview Redis is an excellent key/value cache that is used across many of Shokunin's customers. While redis is an great piece of software it is often difficult to obtain information about actually running it in production from an operational perspective. This article aims to discuss the necessary steps that ops teams should take before running redis in a production envir
Redis new data structure: the HyperLogLog - <antirez>
Generally speaking, I love randomized algorithms, but there is one I love particularly since even after you understand how it works, it still remains magical from a programmer point of view. It accomplishes something that is almost illogical given how little it asks for in terms of time or space. This algorithm is called HyperLogLog, and today it is introduced as a new data structure for Redis. Co
Redis cluster, no longer vaporware. - <antirez>
The first commit I can find in my git history about Redis Cluster is dated March 29 2011, but it is a “copy and commit†merge: the history of the cluster branch was destroyed since it was a total mess of work-in-progress commits, just to shape the initial idea of API and interactions with the rest of the system. Basically it is a roughly 4 years old project. This is about two thirds the whole hist

Twilio incident and Redis - <antirez>
Twilio just released a post mortem about an incident that caused issues with the billing system: http://www.twilio.com/blog/2013/07/billing-incident-post-mortem.html The problem was about a Redis server, since Twilio is using Redis to store the in-flight account balances, in a master-slaves setup, with multiple slaves in different data centers for obvious availability and data safety concerns.
