[Video Podcast] Improving Valkey with Madelyn Olson

"And so I'll start by giving a little bit of history before the actual creation of Valkey. So I actually was a maintainer of the open source Redis project since about 2020. So me and some of the other major contributors of Redis had kind of built a pretty exciting development community. And so when Redis decided to change their license, so back in 2024 in March, Redis moved from an open source permissive BSD license to a commercial license, SSPL and variant called RSAL."

"Thomas Betts: Hello, and welcome to the InfoQ Podcast. I'm Thomas Betts. Today I'm speaking with Madelyn Olson. Madelyn is the maintainer of the Valkey project and a principal software development engineer at Amazon ElastiCache and Amazon Memory DB, focusing on building secure and highly reliable features for the Valkey engine. She recently gave a deep dive technical presentation at QCon San Francisco about recent changes to the Valkey hash table and the associated performance improvements."

Valkey originated when major Redis contributors sought to continue collaborative development after Redis switched its license from permissive BSD to commercial SSPL/RSAL in March 2024. Contributors from companies including Alibaba, Ericsson, Tencent, Huawei, and Google joined Redis community maintainers to create Valkey under the Linux Foundation. The project aims to provide an open-source alternative and continue development of an in-memory key-value engine. The Valkey engine emphasizes secure, highly reliable features and recent technical work includes changes to the Valkey hash table and related performance improvements presented at a major conference.
