Axe 4: Promises/Futures

Promises/Futures

background

La ludification a introduit une pression globalement plus forte à de multiples endroits de la plateforme. Durant les opérations de scoring, étape essentielle du jeu, de nombreuses informations doivent être écrites pour mettre à jours les scores des joueurs, leurs statistiques, les statistiques internes à la plateforme, ainsi que d’autres données concernant l’état du joueur dans le jeu en cours.
Il s’agit d’une matrice importante d’informations: pour chaque joueur, chaque opération de scoring provoque au minimum 97 opération d’écritures en base de données, jusqu’à 120 dans certains cas, et au moins 3 opérations de lecture.
En moyenne, chaque match compte 180 opportunités de prédiction (GuessOpportunity), chacune de celle ci comporte au minimum 100 prédictions (Guess).

La figure suivante représente une partie des opérations de lecture/écriture lors du scoring d'une prédiction d'un joueur.
