ClickHouse Table Functions

A core ClickHouse concept to be aware of is table functions. These are essentially functions which create a table abstraction over some data source, in a way that they can be used within the FROM clause of a query.

Two examples we will be using in this lesson are the URL and the S3 table functions.
