* bikin lemot 30s timeout karena ada 2 join di rows yang banyak
* solution: indexing column
* show index from t_gps_tracks_address;
* create index addr_device_id on t_gps_tracks_address (device_id);
* create index addr_master_id on t_gps_tracks_address (master_id);
* show index from t_gps_tracks;
* create index tracks_device_id on t_gps_tracks (device_id);
* show index from t_vehicles;
* create index vhc_device_id on t_vehicles (device_id);
*
* solution not working. Don't reinvent the wheel
* create view. not working
