Class GameStats.CalculateSpammyUsers

  • All Implemented Interfaces:
    java.io.Serializable, org.apache.beam.sdk.transforms.display.HasDisplayData
    Enclosing class:
    GameStats
    public static class GameStats.CalculateSpammyUsers
extends org.apache.beam.sdk.transforms.PTransform<org.apache.beam.sdk.values.PCollection<org.apache.beam.sdk.values.KV<java.lang.String,​java.lang.Integer>>,​org.apache.beam.sdk.values.PCollection<org.apache.beam.sdk.values.KV<java.lang.String,​java.lang.Integer>>>
    Filter out all users but those with a high clickrate, which we will consider as 'spammy' users. We do this by finding the mean total score per user, then using that information as a side input to filter out all but those user scores that are larger than (mean * SCORE_WEIGHT).
