Results index schema details

As we have already hinted, inside the results index, there are a variety of different documents, each with their own usefulness with respect to understanding the results of the anomaly detection jobs. The ones we will discuss in this section are the ones that directly relate to the three levels of abstraction that we discussed previously in this chapter. They are aptly named as follows:

  • result_type:bucket: To give bucket-level results
  • result_type:record: To give record-level results
  • result_type:influencer: To give influencer-level results

The distribution of these document types will depend on the ML job configuration and the characteristics of the dataset being analyzed. These document types are written with the following heuristic:

  • result_type:bucket: One document is written for every bucket span's worth of time. In other words, if the bucket span is 15 minutes, then there will be one document of this type being written...
