Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

In-memory storage backend for single-process deployments.

All storage components use thread-safe in-memory data structures. State is not shared across processes and is lost on restart.

Memory backend is also used as the fallback layer for Redis backend when Redis is unavailable.

Examples:

backend = Memory::Backend.new(clock: SystemClock.new, config:)
backend.state_store #=> Memory::Storage::State
