Pipeline aggregation doesn't deduplicate underlying aggs #26611
Description
Kibana version: 6.5.1
Steps to reproduce:
- Define two pipeline aggregations as metrics on the same underlying bucketing aggregation
- Kibana will ask both aggs to be calculated
Expected behavior: Kibana should deduplicate the same underlying aggregation and only run them once.
Screenshots (if relevant):
Imagine asking for both avg and max buckets, underlying request then looks like:
{
"aggs": {
"1": {
"max_bucket": {
"buckets_path": "1-bucket>_count"
}
},
"2": {
"avg_bucket": {
"buckets_path": "2-bucket>_count"
}
},
"1-bucket": {
"date_histogram": {
"field": "Date",
"interval": "1M",
"time_zone": "Europe/Berlin",
"min_doc_count": 1
}
},
"2-bucket": {
"date_histogram": {
"field": "Date",
"interval": "1M",
"time_zone": "Europe/Berlin",
"min_doc_count": 1
}
}
