Struct DocActivityMetrics 

Source 
pub struct DocActivityMetrics {
    pub id: Uuid,
    pub last_read_timestamp: StatisticValue,
    pub last_write_timestamp: StatisticValue,
    pub read_count: StatisticValue,
    pub write_count: StatisticValue,
}
Expand description

DocActivityMetrics stores key document activity features, which are used to recommend relevant documents to the user. Here’s a walkthrough of the recommendation procedure: collect 1k most recent document events (write/read), use that activity to construct a DocActivtyMetrics struct for each document. Min-max normalizes the activity features, then rank the documents.

Fields§

§id: Uuid§last_read_timestamp: StatisticValue

the latest epoch timestamp that the user read a document

§last_write_timestamp: StatisticValue

the latest epoch timestamp that the user wrote a document

§read_count: StatisticValue

the total number of times that a user reads a document

§write_count: StatisticValue

the total number of times that a user wrote a document
