The AIS decoder system has been up and running since March 2012. Since then database table have been growing up at a good rate. This year I decided to clean up the system before everything goes bananas.

The ais_stat_data table was really huge and it was really mandatory to cut some lines and make it lighter and faster.

Some old and unuseful tables were removed and data was stored in a safe place. After the cleaning database looks more “fit” and light.

The system is now up ‘n running and is ready to face 2017 AIS messages. Stay tuned!
