Leaderboard in DynamoDB
• Hash key = Primary key • Range key = Sub key • Others attributes are
unstructured, unindexed • So… How to sort based
on Top Score?
AWS Gaming Solutions | GDC 2014
Leaderboard with Secondary Indexes
• Create a secondary index! • Set hash key to Game Level • Set range key to Top Score • Can now query by Level,
Sorted by Top Score • Handles any (sane) gaming
use case

Python Leaderboard
table = Table('scores', schema=[ HashKey('user'), RangeKey('level') ], throughput={ 'read': 5, 'write': 15 }, global_indexes=[ GlobalAllIndex('highscore', parts=[ HashKey('level'), RangeKey('score', data_type=NUMBER) ], throughput={ 'read': 5, 'write': 15 } ) ])
new_score = Item(table, data={ 'user': user, 'level': level, 'score': score }) new_score.save() topscores = table.query(index='highscore') for ts in topscores: print(ts['user'], ts['score'])
