Bucket aggregations compute bucket doc_count values by incrementing the doc_count by 1 for every document collected in the bucket. When using summary fields (such as aggregate_metric_double) one field may represent more than one document. To provide this functionality we have implemented a new field mapper (named doc_count field mapper). This field is a positive integer representing the number of documents aggregated in a single summary field. Bucket aggregations will check if a field of type doc_count exists in a document and will take this value into consideration when computing doc counts.

heya, heads up that you will need to adapt the valueFetcher method to take a QueryShardContext instead MapperService as argument, following #64524 . Our streams have crossed in master and it caused an interesting situation where both our builds were green yet the code after the two merges would not compile :) |

After merging _doc_count PR in 7.x (elastic#64594), we can enable the skipped ML dataframe analytics. Those tests had been broken after merging elastic#64503 in master
