                    "type": "geo_point"
                },

Have you tried creating individual documents per element of route from an array?

In your browsers dev tools, can you open the network tab. You should see a request to fetch the tooltip fields when you mouse over a marker. What does this request return?

Hello,

I tried creating individual documents for each co-ordinates of a route (array). I could get the tool tip with timestamp as you mentioned. Ex:

If we create individual documents for each co-ordinates of a route, I am bit worried about the scalability as I have million of routes with each route has approx 500 - 1000 co-ordinates. whats your view ?

Thanks for your support !!!

I do not think there is a performance difference from storing objects in an array vs breaking those objects into multiple documents. In either case, Elasticsearch is indexing the properties of objects in the array, https://www.elastic.co/guide/en/elasticsearch/reference/current/array.html.

You need to map the field as date in order for Kibana to treat the field as a date and format the the value as expected.

ok, I will go ahead with breaking co-ords and index as separate documents with field as date, Many thanks for your support.
