The following topics are included in the official exam objectives but these are missing in the labs of Engineer I and II training labs.
Write and execute pipeline aggregations
Use the scroll API to retrieve large numbers of results
*Configure an index that implements a parent/child relationship
Are these topics included in the exam ?
Also, training labs list CCR as an exam prep topic but it is not included in the exam objective. Is it correct to assume that only CCS is included in exams ?
Nothing to do with the functionality or the usefulness of pipeline aggs - they are an awesome feature of the Query DSL! It was strictly based on logistics: we no longer teach that topic in our Engineer training courses because there just wasn't enough time to cover it properly.
