The evolution of Kami’s data infrastructure

Chuan-Zheng Lee, Head of Data at Kami

Kami’s new clickstream database (discussed in Jordan’s talk) was set to open a new world of product analytics. But to make the most of it, it would need to be integrated with other data from production databases. In this talk, Chuan-Zheng will explain how Kami’s data infrastructure evolved over time to facilitate the company’s growing analytics needs. This includes connections from PostgreSQL and CockroachDB to ClickHouse, how ClickHouse works with some major data use cases, as well as how queries for key metrics such as monthly active users have changed to keep up as Kami’s data warehouse grew from 4 TB to over 200 TB.
