We’re thrilled to announce the general availability of Valkey v8.1 in Redis OSS compatible Heroku Key-Value Store .

To add to this excitement, we’re bringing powerful new module capabilities to v8.1, with Valkey Bloom and ValkeyJSON.
For years, Heroku customers have relied on our managed in-memory data store services for caching, session management, real-time leaderboards, queueing, and so much more. Valkey is a drop-in, open-source fork of Redis OSS at v7.2, maintained by the Linux Foundation, and is backwards compatible with Redis OSS protocols…

Today we’re pleased to announce general availability of Heroku Redis with a number of new features and a more robust developer experience. By giving developers a different data management primitive, we’re helping them meet the needs of building modern, scalable applications. The classic example of using multiple data stores in an application is the e-commerce site that stores its valuable financial information in a relational database while the user session tokens are saved in a key-value store like Redis. This is one of the use cases where Redis has proven to be instrumental in solving problems like…
