Crocdb -

1. Overview & Definition CrocDB is an open-source, lightweight, and high-performance key-value database written in Go. Its name is a playful nod to "Redis" (like the reptile) while emphasizing its distinct architectural choices. CrocDB is designed for developers who need a fast, embedded database that combines the low-latency benefits of an in-memory store with the durability of on-disk persistence.

| Command | Description | Example | |---------|-------------|---------| | SET key value [TTL seconds] | Stores a value. | SET user:100 "john" TTL 60 | | GET key | Retrieves a value. | GET user:100 | | DEL key [key...] | Deletes one or more keys. | DEL user:100 user:101 | | EXISTS key | Returns 1 if key exists. | EXISTS user:100 | | KEYS pattern | Lists keys matching a glob pattern (scan-only, O(N)). | KEYS user:* | | FLUSH | Clears all data. | FLUSH | | SAVE | Triggers an immediate snapshot. | SAVE | | PING | Health check. | PING | crocdb
