● The third-largest payment
provider in China behind
Alipay and WeChat
Payment
● 500 million registered users
and 41.9 million active users
● Need to improve the
efficiency of fraud detection
for mobile payments
● Current lambda architecture
of Kafka + Hive is complex

four)
● Improve production
efficiency by 11 times
● Higher stability due to the
unified architecture
Why Pulsar
● Cloud-native architecture
and segment-centric
storage
● Pulsar is able to do both
streaming and batch
