Data Collection

• Mobile Devices

• Game Servers

• Ad Networks

• Size of event ~ 1 KB

• 500M+ events/day

• 500G+/day & growing

• JSON format

Source of Data Data Size & Growth

Database Schema

• Every game – database schema

• Each game event = table (e.g., battle_fight, iap)

• 40-50 tables per DB schema

• All game titles ~ 1000 tables in DW

Key Requirements

• Data collection & streaming to database

• Zero data loss

• Zero data corruption

• Guaranteed data delivery

Cost of maintenance - HIGH

Challenges

• Hard to maintain and scale

• Spike in Live Ops events can clog other events

• Difficult to add new sink

• Writes to DW impacted query performance for BI

users

• Poor data latency

Key Requirements – the list grew

• Data collection &

streaming to database

• Zero data loss

• Zero data corruption

• Guaranteed data

delivery

• Near real-time data latency

• Real-time ad-hoc analysis

• Ease of adding consumers
