Create the num
field as long with auto-mapping.
PUT coerce_test/_doc/1
{
"num": 1
}
By default, coerce is true. That means a string value which can be converted into a number, can be ingested.

In order to render the Other slice, Kibana uses the sum_other_doc_count
value in the response. That works if the metric is Count
.
But what if we use different metric aggretation to define the size of each slice?
For example, this pie chart uses sum of field age
. But still, Kibana is able to show the Other slice as expected.
When I looked at Chrome dev tool network tab, there were 2 _search

Elasticsearch 7.11 から Runtime Field が使えるようになったり (まだ Beta だけど)、 Kibana の Painless Lab でオートコンプリートが使えたりするので、 Painless の出番は今後ますます増えてくるでしょう。練習も兼ねて、使えそうなスニペットをまとめていきたいと思います。
7.12 で Grok と Dissect が使えるようになるみたい、楽しみだ!
