PikiwiDB (Pika) is a Redis-compatible, persistent key-value database built on RocksDB, developed by Qihoo's infrastructure team. It speaks the Redis protocol and data structures while removing Redis's memory-capacity limits, supporting master-slave replication and Codis-based clustering.

Use cases

• store more data than fits in Redis memory
• replace Redis for datasets over 16GiB
• run a persistent Redis-compatible KV store
• migrate from Redis without changing clients
• set up master-slave replication with full and incremental sync
• scale a Redis-like store horizontally with Codis

When to choose

• your Redis dataset exceeds memory capacity or costs too much in RAM
• you need Redis protocol compatibility with disk-backed persistence
• long startup recovery times of in-memory Redis are a problem

When to avoid

• you need ultra-low-latency pure in-memory caching
• you rely on Redis features PikiwiDB does not implement
• you want a fully managed cloud database
