GENERATING METRICS FOR CONTENT ITEMS PRESENTED IN AN ONLINE SYSTEM

摘要

An online system allows creators and owners of content items presented within the system to view real-time metrics related to the content items. The online system stores data describing user interactions with content items in one or more activity logs and processes the activity logs in a distributed manner activity to identify user interactions with content items. For example, activity logs are divided into several portions that are processed in parallel using aggregation operators to generate user interaction aggregations. An aggregation includes one or more user interactions associated with the same content item and sharing certain criteria. From the user interaction aggregations, the online system determines one or more requested metrics, and may combine user interaction aggregations related to different content items when computing metrics.

1. A method comprising:
generating, by an online system, an interaction aggregation for a content item presented by the online system, the interaction aggregation identifying one or more users that interacted with the content item; receiving, from a third party system, a request for a metric describing interactions with the content item; identifying, in response to the request, a set of interactions stored by the online system not included in the generated interaction aggregation; generating, for the content item, one or more intermediate aggregations from the set of interactions to identify additional interactions with the content item not included in the interaction aggregation; combining the one or more intermediate aggregations with the generated interaction aggregation into a combined aggregation to update the generated interaction aggregation with the additional interactions with the content item; and generating a value for the metric based on the combined aggregation.
