This interface provides a unified abstraction for different memory backend implementations, + * enabling consistent interaction patterns across various memory storage systems. It supports + * both conversation management and detailed trace data storage for comprehensive agent behavior + * tracking.

+ * + *

Supported Memory Types:

+ *
    + *
  • Agentic Memory - Local cluster-based intelligent memory system
    • + *
  • Remote Agentic Memory - Distributed agentic memory implementation
    • + *
  • Bedrock AgentCore Memory - AWS Bedrock agent memory integration
    • + *
  • Future memory types - Extensible for additional implementations
    • + *
+ * + *

Core Capabilities:

+ *
    + *
  • Message retrieval in standardized ChatMessage format
    • + *
  • Conversation and session management
    • + *
  • Interaction persistence with metadata support
    • + *
  • Tool execution trace data storage
    • + *
  • Dynamic interaction updates
    • + *
+ * + *

Note: ConversationIndex uses a separate legacy pipeline for backward compatibility + * and is not part of this modern interface hierarchy.
