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. The service substitutes them into namespace templates during long-term memory extraction. Up to five keys can be defined per memory resource, each referenceable across multiple strategies.

Flexible namespace variables are available today in all AWS Regions where Amazon Bedrock AgentCore Memory is generally available, at no additional cost. To get started, see Specify long-term memory organization with namespaces in the Amazon Bedrock AgentCore Developer Guide.
