Single KeyDB Node Achieves Thoughput of a 7 Node Redis Cluster

October 28, 2019

KeyDB Support

KeyDB is a high performance fork of Redis that’s able to hit 1,000,000 ops/sec on a single node, without sharding. This article not only discusses the performance, but the benefits that go along with it. More power means less moving parts to do the same job, and the semantics of that statement are worth discussing.

Rethinking the Redis EXPIRE command

October 21, 2019

KeyDB Support

This article discusses several changes we have made to the EXPIRE command and how it works. We have added the ability to expire individual members of a set with the EXPIREMEMBER command and have also enabled active deletion to operate in near real time which has big advantages for those who rely heavily on using expires in production. Throughout the work with the EXPIRE command we have actually achieved 5-10% memory savings with these.

A Multithreaded Fork of Redis That’s 5X Faster Than Redis

October 7, 2019

KeyDB Support

What if I told you there is a fork of Redis that can run 5x faster with nearly 5x lower latency. What if you no longer needed sentinel nodes and your replicas could accept both reads and writes? This could provide the potential to achieve a 10x reduction in the amount you shard.

What can you get today for under $1? Would you guess 23 billion ops out of your Database?

September 9, 2019

KeyDB Support

Today ARM processors are becoming a cost effective way of computing providing great bang for your buck… and now they are in the cloud! This begs to question whether your setup is still the most economical means for serving your customers.

Eliminating the Need for Redis Sentinel with KeyDB Active Replication

August 29, 2019

KeyDB Support

Active Replication eliminates the need for having ‘monitoring sentinel nodes’ to decide when to perform failovers in a high availability setup. This also enables your active replica node to accept reads and writes while actively syncing with the other active replica node.

Running KeyDB on Arm-based Amazon EC2 A1 Instances for the Best Price/Performance

August 19, 2019

KeyDB Support

We’ve talked to many of our users who were looking to optimize their cost on AWS. While most had experimented with the many available x86 based instance types we were surprised that few had tried the Arm-based Amazon EC2 A1 instances. These Arm-based instances come with unique performance advantages for multi-threaded cache server workloads. To understand why cache databases, and KeyDB specifically, is uniquely suited to Arm we have to first understand a little about the hardware.

Redis Replication and KeyDB Active Replication: Optimizing System Resources

August 5, 2019

KeyDB Support

A lot sites run replica nodes for high availability of their servers. Makes sense, but is this replica being fully utilized? Or are you just paying for high availability without getting the performance boost of essentially doubling your resources? This article discusses options used with Redis, as well as the active-replication option used in the Redis compatible database KeyDB.

How Fast can A Single Instance of Redis be?

June 17, 2019

KeyDB Support

Redis is known as one of the fastest databases out there. But what if some of the limitations were removed, how fast could a stand-alone instance become? We often hear that Redis will likely become network bound or memory bound before it is CPU bound on performance limitations. Depending on your setup it could be any of these.

In this article we are going to discuss how we made a module that nearly doubles Redis performance!

A Brief History of Existential Threats to Open Source

March 11, 2019

KeyDB Support

How times have changed. In the early 2000s Steve Ballmer famously called Linux a “cancer”. But Microsoft was not the biggest threat. A debate was raging that threatened to sow confusion, fracture the community, and derail open source as a whole. Should people who modify open source software be required to open source their changes as the GPL requires? Or should they be free to do as they wished even if that meant keeping their changes proprietary? The fight was over developer freedom vs user freedom, with the Free Software Foundation in one ring, and Apache Software Foundation in the other. Without a united front open source was doomed — or so Microsoft hoped.
