index_object:delete()

index_object

Delete a tuple identified by a key.

Same as box.space...delete(), but key is searched in this index instead of in the primary-key index. This index ought to be unique.

Parameters:

• index_object (index_object) — an object reference.

• key (scalar/table) — values to be matched against the index key

Returns

the deleted tuple.

Return type

tuple

Note regarding storage engine: vinyl will return [nil]{.title-ref}, rather than the deleted tuple.
