## Type : Automation - periodic database cleanup (P3 - performance) ##
|
|
## --------------------------------------------------------------------------- ##
|
|
## Scop : Tabelele care cresc nelimitat (rapoarte de lupta, chat, ##
|
|
## mesaje sterse de ambele parti) incetinesc in timp intreg ##
|
|
## serverul si umfla backup-urile. Aici le taiem periodic, ##
|
|
## dupa reguli de retentie configurabile. ##
|
|
## --------------------------------------------------------------------------- ##
|
|
## Reglaje in GameEngine/config.php (0 = dezactivat pentru fiecare): ##
|
|
## define('CLEANUP_REPORTS_DAYS', 14); // rapoarte NEARHIVATE mai vechi ##
|
|
## define('CLEANUP_CHAT_DAYS', 7); // mesaje de chat mai vechi ##
|
|
## define('CLEANUP_MESSAGES_DAYS', 0); // mesaje sterse de AMBELE parti ##
|
|
## define('CLEANUP_INTERVAL', 3600); // la cat timp ruleaza curatenia ##
|
|
## define('CLEANUP_BATCH', 5000); // randuri sterse per tabel/rulare ##

/**
|
|
* Curatenie periodica in tabelele care cresc nelimitat.
|
|
*
|
|
* Rulata din lista de metode a constructorului, deci ar fi apelata la
|
|
* fiecare tick. Nu vrem asta: stergerile sunt scumpe, iar datele nu se
|
|
* strang atat de repede. De aceea metoda are propriul interval (implicit o
|
|
* data pe ora), tinut intr-un fisier marker din Prevention/.
|
|
*
|
|
* Stergerile sunt facute in LOTURI (LIMIT), ca sa nu blocam tabelele minute
|
|
* intregi la prima rulare pe un server vechi cu milioane de randuri: ce nu
|
|
* intra intr-o rulare se sterge la urmatoarele, pana se ajunge din urma.
