Amazon Bedrock AgentCore Memory now lets developers define flexible namespace variables to scope long-term memories along any application-specific dimension - such as organization, tenant, team, or environment - without creating duplicate strategies or overloading built-in variables. This gives multi-tenant and complex-hierarchy applications fine-grained control over how memories are organized, isolated, and accessed. Define keys on the memory resource, reference them in a strategy’s namespace template, and supply values at runtime through the CreateEvent API.
