Title: Query Optimization At Snowflake

In this talk, I will give an introduction to Snowflake’s query optimizer. I will talk about the main features of Snowflake’s optimizer, explain the main philosophy behind the design decisions, and delve into some unique aspects of the implementation. I will also later expand into our infrastructures to facilitate optimizer development and discuss the opportunities and challenges for implementing and rolling out query optimizations for cloud-based databases.
