Unique count metric for array of fields

Elastic Stack Kibana
1

After aggregation I have documents with below structure in a bucket.

{ ... array: [ { ... }, { ... }, { key: value } ] }

Can I somehow apply unique count metric for key field? Thanks.

P.S

Does this limitation mean I can't do aggregation or perform metrics on key fields/values like below ?

{ ... array: [ { ... }, { ... }, { key: value } ] }

{ ... array: [ 'key1', ' key2' ] }

Unfortunately the format of your data is incompatible with Kibana's ability to run unique count metrics. Could you restructure your data so that it's not inside an array?
