#key_set ⇒ ::Google::Cloud::Spanner::V1::KeySet

Returns Required. key_set identifies the rows to be yielded. key_set names the primary keys of the rows in table to be yielded, unless index is present. If index is present, then key_set instead names index keys in index.

It is not an error for the key_set to name rows that do not exist in the database. Read yields nothing for nonexistent rows.
