            return new ObjectMapperProvider().get().readValue(jsonParser, TestingColumnHandle.class);
        }
    }).addDeserializer(Type.class, new TestingTypeDeserializer(typeManager)).addSerializer(Block.class, new TestingBlockJsonSerde.Serializer(blockEncodingSerde)).addDeserializer(Block.class, new TestingBlockJsonSerde.Deserializer(blockEncodingSerde)));
    TupleDomain<ColumnHandle> tupleDomain = TupleDomain.all();
