> With the re-designed dag, we need to define and impl a new MDT Index Record generator which takes in HoodieData<WriteStatus> and outputs HoodieData<HoodieRecord> which are the records required to be ingested to MDT. 
> This should be a flatMapFunction, since a single WriteStatus could return more than 1 record to ingest into MDT for various partitions in MDT
