Java-Action-Storage is a core component of the LightJason multi-agent framework designed to handle the end-to-end persistence of agent actions. It defines a generic ActionStorage interface with adapters for popular databases and file systems, supports asynchronous and batched writes, and manages concurrent access from multiple agents. Users can configure storage strategies, query historical action logs, and replay sequences to audit system behavior or recover agent states after failures. The module integrates via simple dependency injection, enabling rapid Adoption in Java-based AI projects.
