Interface D1StorageOptions

D1 binding from the Worker/DO environment.

Additional storage domains composed over the D1Store default, such as notifications and thread state, which @mastra/cloudflare-d1 does not ship, so they are flowsafe-owned D1 impls. Injected rather than imported so this lower layer never depends on signals/ (which imports do-runner) — build them with createSignalStorageDomains() and pass them here. The default workflow domain supports explicit initial-admission scopes; false/custom workflow overrides retain precedence. workflowDefinitions and knowledge are injectable through this seam on the same terms: @mastra/cloudflare-d1 backs neither, so each resolves undefined unless a host supplies one.

Storage instance id. Default: 'flowsafe'.

Mastra-compatible SQL identifier prefix of at most 39 characters, or empty.
