Valkey -- " is an open source (BSD) high-performance key/value datastore that supports a variety of workloads such as caching, message queues, and can act as a primary database. Valkey can run as either a standalone daemon or in a cluster, with options for replication and high availability. Valkey natively supports a rich collection of datatypes, including strings, numbers, hashes, lists, sets, sorted sets, bitmaps, hyperloglogs and more. You can operate on data structures in-place with an expressive collection of commands. Valkey also supports native extensibility with built-in scripting support for Lua and supports module plugins to create new commands, data types, and more."

Alternatives to Redis

Garnet from Microsoft is a redis protocol (RESP) compliant remote cache-store. Garnet is thread-scalable within a single node. It also supports sharded cluster execution, with replication, checkpointing, failover, and transactions. It can operate over main memory as well as tiered storage (such as SSD and Azure Storage). Garnet supports a rich API surface and a powerful extensibility model. one can use Garnet with unmodified Redis clientsavailable in most programming languages. Blog post - A brief history of Garnet
