Sub Aggregations in java API client

Elastic Stack Elasticsearch
1

Hi,
I am trying to rewrite our code for building multiple aggregations to using the new java API client 7.16.3.
I can't find an example for sub aggregations

TermsAggregationBuilder aggregationBuilder AggregationBuilders.terms(aggregateBy.getAttributeName()); aggregationBuilder.subAggregation(...

How to construct this with a new client?

 TermsAggregation.Builder termsBuilder = AggregationBuilders.terms(); termsBuilder.field(aggregateBy.getAttributeName()); termsBuilder.name(aggregateBy.getAttributeName()); termsBuilder.build()._toAggregation().aggregations( ???

Thanks

Hi @Anna_Mikhilev

I did this example, maybe help you.

 Map<String, Aggregation> map = new HashMap<>(); Aggregation subAggregation = new Aggregation.Builder() .avg(new AverageAggregation.Builder().field("revenue").build()) .build(); Aggregation aggregation = new Aggregation.Builder() .terms(new TermsAggregation.Builder().field("director.keyword").build()) .aggregations(new HashMap<>() {{ put("avg_renevue", subAggregation); }}).build(); map.put("agg_director", aggregation);
