>
> In IoT scenarios, it's common to use device_id and timestamp to identify a
> record of the device data.
> When storing these records with hoodie, we usually use the
> device_time(timestamp format) as the partition field，device_id and
> device_time as record key.
> however, TimestampBasedKeyGenerator supports only SimpleKey, and
> ComplexKeyGenerator does not support the timestamp-based partition path. So
> we need a new KeyGenerator to support partition path in timestamp format and
> complex key.
