 """Remove the key-value entry for a given key in Couchbase. :param key: A string which is the key to remove. The format and type of the key follows the same conventions as in :meth:`upsert` :type key: string, dict, or tuple/list :param int cas: The CAS to use for the removal operation. If specified, the key will only be removed from the server if it has the same CAS as specified. This is useful to remove a key only if its value has not been changed from the version currently visible to the client. If the CAS on the server does not match the one specified, an exception is thrown. :param boolean quiet: Follows the same semantics as `quiet` in :meth:`get` :param int persist_to: If set, wait for the item to be removed from the storage of at least these many nodes :param int replicate_to: If set, wait for the item to be removed from the cache of at least these many nodes (excluding the master) :raise: :exc:`.NotFoundError` if the key does not exist. :raise: :exc:`.KeyExistsError` if a CAS was specified, but the CAS on the server had changed :return: A :class:`~.Result` object. Simple remove:: ok = cb.remove("key").success Don't complain if key does not exist:: ok = cb.remove("key", quiet=True) Only remove if CAS matches our version:: rv = cb.get("key") cb.remove("key", cas=rv.cas) Remove multiple keys:: oks = cb.remove_multi(["key1", "key2", "key3"]) Remove multiple keys with CAS:: oks = cb.remove({ "key1" : cas1, "key2" : cas2, "key3" : cas3 }) .. seealso:: :meth:`remove_multi`, :meth:`endure` for more information on the ``persist_to`` and ``replicate_to`` options.
