Is your feature request related to a problem?

The current fixed SQL schema limits flexibility and optimization for specialized use cases. Being able to define custom tables and relationships would allow users to model memory in a way that better fits their specific requirements.

Describe the solution you'd like

Support a user‑configurable SQL schema, allowing users to define their own tables and relationships for memory storage, rather than relying on a single generalistic hardcoded schema.

Describe alternatives you've considered
