Databases
Valkey (Redis)
An in memory cache and very fast message queues, compatible with the Redis protocol.
What Valkey (Redis) covers
Minimal response times
Data lives in memory, which puts response times under a millisecond and takes load off your relational database.
Cache, queues and counters
The same service acts as an application cache, a task queue and a real time counter. One component to operate instead of three.
Redis protocol
Your Redis client libraries work as they are. There is no code to rewrite to benefit from it.
