Tenant Virtualization

Astra supports virtual tenant keyspaces by prefixing keys with:

/__tenant/<tenant_id>/...

Where It Is Applied

• Online API path: request tenant identity from auth claim.
• Migration path (astra-forge converge): explicit tenant IDs per source snapshot.

Why It Matters

• Enables multi-tenant disaggregation with overlapping raw key names.
• Prevents cross-tenant key collision during convergence and steady-state operation.

Guardrails

• Auth and tenant claim mapping must be configured consistently.
• Migration validation must include per-tenant key parity and marker checks.
