Any attempts to interact with the schema will throw an exception.
For example the historical map data type uses this as follows:
Map<ByteString, List<Struct>> historicalMap =
resultSet.getMap(
"cf",
SqlType.mapOf(SqlType.bytes(), SqlType.arrayOf(SqlType.struct())));
Struct struct = historicalMap.get("column").get(0);
// Struct schema will be validated here so there's no need for users to pass the schema to getMap above
ByteString value = struct.getBytes("value");
