vector
delete
Delete one vector key.
strata vector deletedb.vectors.delete(collection: 'str', key: 'str') -> 'Any'wire vector_delete
Deletes one visible vector entry from a collection. Missing keys are represented as no-op mutation acknowledgements.
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.
