Hello,

There is any functionality that allows implementing funnels and retention queries in clickhouse ?

For example, a funnel could include these steps:

• Step1: Count the number of unique users who registered in timeframe X.
• Step2: Of the users who were counted in step 1, count the number of them who created content in that timeframe
• Step3: Of the users who were counted in step 2, count the number of them who shared content in that timeframe

Supposing that the information is available in 3 different tables (registration, created_content, shared_content) and the common key is user_id what's the optimal way to implement this?
