Amazon Bedrock AgentCore Memory announces metadata for long-term memory

Amazon Bedrock AgentCore Memory now supports metadata on long-term memory (LTM) records, enabling agents to tag, filter, and retrieve memories using structured attributes alongside semantic search. You can define up to ten indexed keys per memory resource - with support for STRING, NUMBER, and STRING_LIST types - and use different operator types to filter retrieval results. Metadata can be attached to events at ingestion time or inferred automatically by the LLM based on extraction instructions you define on the memory resource.
