WARNING: Segment doesn't actually guarantee that message_id is unique. If you capture and insert the message_id into another table, you will see that the same message_id is reused. We recommend that you concatenate the timestamp with a message_id to create a unique id.

Processing Configuration:

  • Run After: Started Session
    Why? Setting this transformation to run after the session will ensure that page views will be used to define sessions only AFTER the identity resolution is applied.



Started Session

A customer Started a session in your product. A session defined by google is 30 minutes of inactivity

Why do we subtract 1 second from the session?

We are using the first page_view to represent a session but technically a session starts right before that. We subtract 1 second to handle that case. This ensures that saying give me all page views after a session returns the first page view too.

Enriched Activities: viewed_page, viewed_product, and started_session
Why?
All of these activities have the same activity_id because they are based on page views.
