Pika, a persistent, Redis compatible key value datastore backed by RocksDB, ready to serve on first boot.
Pika is a large capacity, persistent key value datastore that speaks the Redis wire protocol but keeps data on disk with RocksDB instead of in memory. A single node can serve very large keyspaces on commodity storage, and any Redis client connects unchanged. It is used for caching, session storage, queues and low latency access to datasets far larger than RAM.
cloudimg ships Pika hardened and fully patched on Ubuntu 24.04 LTS, with the RocksDB dataset on a dedicated data disk and a unique password rotated into each VM on first boot, so there is no shared default credential and no unauthenticated access. 24/7 support is included with every image.
