Lampros Smyrnaios 89ddd5d963 - Add the "shutdownService.sh" script.

Lampros Smyrnaios 41af8cc429 Add counters, in each gathering, for 1) the num of new datasources, 2) the num of updated datasource and 3) the num of added payloads. 2023-07-26 17:32:16 +03:00
Lampros Smyrnaios 1ee1a94eff - Handle the case where the "gatherNumberOfPayloadsPerDatasource()"-query-method is executed while some tables of the DB are in a "merge" state. In this case, the queries fail and the App retries up to 10 times. 
- Handle the case when the aforementioned query-method fails with some unhandleable error. In this case the app retries 1 time and if it fails again, then if this has happened during initialization, the app shuts down, else the incident is ignored and the app will retry after 6 hours when the method is scheduled to run again.

Lampros Smyrnaios 8746d301d5 - Add useful messages for missing parameters in Stats API. 
- Fix the Stats API returning simple numbers as "application/json". Now they are returned as "text/plain".

Lampros Smyrnaios 7e5c338de3 - Improve performance by avoiding checking if the huge ConcurrentHashMap is empty, on every request. After the first data-gathering, it will neven be empty and the checking-code is expensive. 
- In case of an error retrieving data from the DB during initialization, gently shutdown the App. There is no point keeping the app running just to serve 500-Server-Errors.
- Code polishing.
