Do Conversion Funnel Analysis With Databend

Funnel analysis measures the number of unique users who has performed a set of actions, and we use it to see drop-off and conversion in multi-step processes.

Create a Table

CREATE TABLE events(user_id BIGINT, event_name VARCHAR, event_timestamp TIMESTAMP);

Now we have a table with the following fields:

• user_id - a unique identifier for user
• event_name - type of the event, like: login, visit, cart and purchase
• event_timestamp - timestamp which event occurred

Funnel Analysis

It's easy and performance to use Databend WINDOW_FUNNEL Function to find out how far the user user_id could get through the chain in an hour window slides.

SELECT
    level,
    count() AS count
FROM
(
    SELECT
        user_id,
        window_funnel(3600000000)(event_timestamp, 
        event_name = 'login', event_name = 'visit', 
        event_name = 'cart', event_name = 'purchase') AS level
    FROM events
    GROUP BY user_id
)
GROUP BY level ORDER BY level ASC;
