graph
delete
Delete a graph and its visible data.
strata graph deletedb.graphs.delete(name: 'str') -> 'Any'wire graph_delete
Deletes a named graph and every visible node, edge, binding, and ontology row it owns. Deleting a graph that does not exist is not an error: the acknowledgement reports `deleted: false` with a `not_found` effect. Earlier states remain readable through time travel on other commands.
Successful mutations return an acknowledgement of the outcome: for a state-changing write, the affected target with the mutation effect and commit facts; for mutations that produce a domain result (such as a branch or a promotion outcome), that result object.
