[FEATURE] Add support for geo_shape fields

[alisazosimova]

Hi guys!

Is your feature request related to a problem?
Yes. I am trying to create a visualisation (coordinate map), that would aggregate geo data by a geo_shape field type.

I build these objects programmatically mostly, but trying to create a map from Dashboards UI gives the same result.

In my index, I have two fields of geo_shape type:

This field type can be aggregated as Geohash grid aggregation according to Elastic 7.9 documentation
https://www.elastic.co/guide/en/elasticsearch/reference/7.9/search-aggregations-bucket-geohashgrid-aggregation.html#_aggregating_geo_shape_fields

Is some kind of license needed for this now? Does OpenSearch has any capabilities to build maps with geo_shape fields?

This is the error that I see when I try to build a map with that mentioned index from UI:

(as you can see, there's no mention of the geo_shape field type in the list of compatible field types; only geo_point)

OpenSearch Version: 1.1 | Dashboards Version: 1.1

What solution would you like?
Ability to aggregate with geo_shape field type; more precisely: choose GeoObjectGT / GeoObjectDT fields that are of geo_shape type for Geohash / GeohashGrid aggregation.

Hi @alisazosimova
I can see that you want to do the aggregation on the field type geo_shape. We are currently working on building the aggregations on geo_shape. Please refer this github issue for the details.

Once we have the support for doing the aggregations on geo_shape next step would be to enable them from the dashboard UI. I will go ahead and create an issue in the right repository for enabling the aggregations on UI too and will link with the above github issue.
