For any given event, the only metadata and fluxdata collected are those that are selected in the specific data pipe(s) where that event is selected for collection. This allows you to create highly specific data collection strategies from a single collector configuration, significantly reducing data volume without sacrificing valuable insights.

Send a large, context-setting event once, and then follow it with many smaller, minimal events that reference the original context by configuring different data pipes to handle different event payloads:

How It Works: A Practical Example

Data Pipe 1: Initial Session Event

Event: A single, initial event like custom_session_start.
Data: This pipe is configured to collect the full, comprehensive metadata payload. This includes all session-wide context: user details, device information, geo-location, network data, and custom metadata. This event establishes the app_session_id.

Data Pipe 2: Initial Page View Event

Event: This pipe would include events that establish a new, non-video context, such as custom_DOM_pageView.
Data: The payload will include metadata specific to the page-level context (URL, title, etc.) and the app_session_id to link it to the main session. It will exclude the redundant global context data sent in Data Pipe 1.

Data Pipe 3: Subsequent Page Events

Events: This pipe should contain the numerous user interaction events that can happen on a page (e.g., custom_selectMenu, custom_viewCarousel, etc.).
Data: The payload will be minimal, containing only the app_session_id and any metadata unique to that specific action (e.g., custom_menuItemLabel, ongoing session metrics).

Data Pipe 4: Initial Video & Ad Events

Events: Context-setting events like playback_start and ad_impression.
Data: These pipes collect metadata specific to the content or ad being played (e.g., asset_id, ad_creative_id) along with ongoing session metrics. They also include the app_session_id to link back to the main session but exclude the redundant session metadata already sent in Pipes 1 & 2. An identifier is sent here (e.g., content_session_id, ad_id).

Data Pipe 5: Subsequent Playback Events

Events: Frequent, in-playback events like heartbeat, pause, rendition_change, and milestone.
Data: This pipe is configured to be extremely minimal. It collects only the necessary session identifiers (app_session_id, content_session_id, ad_id). All other static metadata is excluded except for ongoing session metrics and any metadata unique to the specific action.

By structuring your data pipes this way, ingress payloads can be filtered to save on egress by sending only the bare essentials on each egressed event. In post-processing, you can easily join the lightweight events back to their heavy payload parent events using the session IDs, creating a complete and detailed record of the user journey for analysis.
