Redislike

Redislike is an in-memory data store and cache designed for low-latency access, inspired by Redis. It provides a compact key-value store with a rich set of in-memory data structures and a simple scripting interface. Redislike is commonly used as a caching layer, a session store, a message broker via its publish/subscribe channel, and a fast data plane for microservices.

The data model includes common Redis-like structures such as strings, hashes, lists, sets, and sorted sets, along with optional support for bitmaps, hyperloglog, and streams. Atomic operations and Lua scripting enable complex updates while maintaining data consistency.

Durability options vary by implementation but typically include optional persistence through periodic snapshots, an append-only log, or a hybrid approach. Some builds prioritize pure in-memory operation with configurable eviction policies to manage memory pressure.

Replication and clustering features aim at high availability and scaling. Many Redislike variants support master-replica replication, automated failover, and cluster mode or sharding to distribute data across nodes.

API compatibility and ecosystem: the command surface is broadly Redis-like, and multiple language clients exist. However, exact command names, semantics, and feature parity can differ between implementations, so compatibility should be verified for a given deployment.

Use cases and performance: Redislike targets sub-millisecond latency for reads and writes, with memory-efficient encodings and careful configuration enabling high throughput. It is commonly deployed as a caching layer, session store, real-time analytics portal, or pub/sub backbone in distributed systems.

Licensing and ecosystem: as with Redis-inspired projects, Redislike projects are typically released under permissive open-source licenses, with a variety of forks and commercial variants in use.
