Akka Memory is a software component designed to provide fast, durable, and in-memory data storage for agentic and distributed systems. It enables agents to reason over time, track progress, and retain context by offering a memory store that is both high-performance and resilient. Data can be scoped to a single agent or shared system-wide, with privacy by default—data never leaves the infrastructure unless explicitly configured. Akka Memory uses sharding to partition application data across in-memory, durable nodes, and automatically rebalances data shards as the number of runtime nodes changes. This ensures low-latency access, high availability, and operational resilience. The memory system is tightly integrated with Akka’s orchestration and agentic runtime, supporting both short-term (session) and long-term memory, and enabling agents to recover, reflect, and reason about past behavior through event logs and replayability. Akka Memory is suitable for use cases requiring distributed, fault-tolerant, and scalable memory for AI agents and other stateful distributed applications.

Key Features

Durable In-Memory Store Provides fast, in-memory storage with built-in durability for agent and system data.
