Clean set, get, and delete methods with optional TTL. Works like memcached, but entirely in-memory.

Keys automatically expire after a configurable TTL. Built-in periodic check cleans expired entries.

Choose between cloning values for safety or storing references for performance.

Built-in tracking of keys, hits, misses, and approximate size in bytes.

Listen for set, del, expired, flush, and flush_stats events to react to cache changes.

All keys stored in a single object for instant O(1) lookups. Practical limit of ~1M keys.
