Why AWS Supports Valkey | Amazon Web Services
AWS Open Source Blog Why AWS Supports Valkey Less than a week after Redis Inc. announced it was removing the open source license and pulling out of the Redis project, Redis contributors banded together to move the community to The Linux Foundation as the Valkey project. They did this almost immediately after the license change announcement went live, in response to community outcry on GitHub and o

Scaling Slack’s Job Queue – Several People Are Coding
Robustly Handling Billions of Tasks in Milliseconds Using Kafka and Redis Slack uses a job queue system for business logic that is too time-consuming to run in the context of a web request. This system is a critical component of our architecture, used for every Slack message post, push notification, URL unfurl, calendar reminder, and billing calculation. On our busiest days, the system processes o

Back To Basics: Hashtables
I wanted to write a post answering the question Why Does Reading From A Hashtable Require Synchronization when I realized that a distinct introduction to hashtables would prove useful. So, here's the first of a few post dedicated to my favorite data structure. Introduction I like to think of Hashtables as flexible arrays. Where arrays rigidly require continuous integer based indexes, hashtables al
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
How Twitter Uses Redis to Scale - 105TB RAM, 39MM QPS, 10,000+ Instances - High Scalability -
Yao Yue has worked on Twitter’s Cache team since 2010. She recently gave a really great talk: Scaling Redis at Twitter. It’s about Redis of course, but it's not just about Redis. Yao has worked at Twitter for a few years. She's seen some things. She’s watched the growth of the cache service at Twitter explode from it being used by just one project to nearly a hundred projects using it. That's many
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
Amazon ElastiCache – Now With a Dash of Redis | Amazon Web Services
AWS News Blog Amazon ElastiCache – Now With a Dash of Redis We launched Amazon ElastiCache about two years ago, and have steadily added features ever since. In the last two years we have added auto discovery, additional cache node types, and reserved cache nodes. We’ve reduced prices several times and we have added support for additional AWS Regions and VPC. Today we are taking a big leap forward
Edis
Edis is a protocol-compatable Server replacement for Redis, written in Erlang. Edis's goal is to be a drop-in replacement for Redis when persistence is more important than holding the dataset in-memory. Edis (currently) uses Google's leveldb as a backend. Future plans call for a multi-master clustering model. Near term goals are to act as a read-slave for existing Redis servers. Learn more → Is Ed
