analyzing customer journey with events data

[gdemontalivet]

I just wanted to share something I built recently to analyze a customer or user journey using events data:

This post assume you have a big table with event type, event timestamp and a user_id. 
I reused some code from this post 
The only thing we need on the modeling side is to get, for each user, what was their first event, second event,... 

SELECT
    events.user_id  AS user_id,
    events.event_type  AS event_type,
    events.created_at AS event_date,
    lead(events.event_type,0) over (partition by user_id order by created_at asc) as first_event,
    lead(events.event_type,1) over (partition by user_id order by created_at asc)as second_event,
    lead(events.event_type,2) over (partition by user_id order by created_at asc) as third_event,
    lead(events.event_type,3) over (partition by user_id order by created_at asc) as fourth_event,
    lead(events.event_type,4) over (partition by user_id order by created_at asc) as fifth_event,
    lead(events.event_type,5) over (partition by user_id order by created_at asc) as sixth_event,
    lead(events.event_type,6) over (partition by user_id order by created_at asc) as seventh_event
FROM  looker-private-demo.ecomm.events  AS events 
GROUP BY
    1,2,3
ORDER BY
    3 DESC

then we just add it to a derived table:

view: sankey {
  derived_table: {
    sql: 
    
    
SELECT
    events.user_id  AS user_id,
    events.event_type  AS event_type,
    events.created_at AS event_date,
    lead(events.event_type,0) over (partition by user_id order by created_at asc) as first_event,
    lead(events.event_type,1) over (partition by user_id order by created_at asc)as second_event,
    lead(events.event_type,2) over (partition by user_id order by created_at asc) as third_event,
    lead(events.event_type,3) over (partition by user_id order by created_at asc) as fourth_event,
    lead(events.event_type,4) over (partition by user_id order by created_at asc) as fifth_event,
    lead(events.event_type,5) over (partition by user_id order by created_at asc) as sixth_event,
    lead(events.event_type,6) over (partition by user_id order by created_at asc) as seventh_event
FROM  looker-private-demo.ecomm.events  AS events 
GROUP BY
    1,2,3
ORDER BY
    3 DESC
;;
  }

  measure: count {
    type: count_distinct
    sql: ${user_id} ;;
  }
  
  dimension_group: event {
    type: time
    sql: ${TABLE}.event_date ;;
  }

  dimension: first_event {
    type: string
    sql: case when ${TABLE}.first_event is null then 'Bounce' else ${TABLE}.first_event end  ;;
  }
  
  dimension: second_event {
    type: string
    sql: case when ${TABLE}.second_event is null then 'Bounce' else ${TABLE}.second_event end  ;;
  }

  dimension: third_event {
    type: string
    sql: case when ${TABLE}.third_event is null then 'Bounce' else ${TABLE}.third_event end  ;;
  }
  
  dimension: fourth_event {
    type: string
    sql: case when ${TABLE}.fourth_event is null then 'Bounce' else ${TABLE}.fourth_event end  ;;
  }
  
  dimension: fifth_event {
    type: string
    sql: case when ${TABLE}.fifth_event is null then 'Bounce' else ${TABLE}.fifth_event end  ;;
  }
  
  dimension: sixth_event {
    type: string
    sql: case when ${TABLE}.sixth_event is null then 'Bounce' else ${TABLE}.sixth_event end  ;;
  }
  
  dimension: seventh_event {
    type: string
    sql: case when ${TABLE}.seventh_event is null then 'Bounce' else ${TABLE}.seventh_event end  ;;
  }

  dimension:user_id {
    type: number
    sql: ${TABLE}.user_id ;;
  }

 
}

Then you can explore it and get this sankey diagram:

you can go further be joining your user table to look at these funnel by device, country,....

This is awesome, thanks for sharing!
