    Return an iterator containing all the key-value pairs which are matched with the given prefix key.

    Return an iterator containing all the key-value pairs which are matched with the given prefix key.

    The operator will provide numColsPrefixKey greater than 0 in StateStoreProvider.init method if the operator needs to leverage the "prefix scan" feature. The schema of the prefix key should be same with the leftmost numColsPrefixKey columns of the key schema.

    It is expected to throw exception if Spark calls this method without setting numColsPrefixKey to the greater than 0.
