Hello, I have incoming data in the below format
"TestItem": {
"OriginCountry": "IN",
"OriginCity": "Banglore",
"DestinationCountry": "US",
"DestinationCity":"New York"}
I want to change the datatype to geo_point so that I can view it in Kibana maps, is this poosible via filters in logstash
(I have created region maps in visualization but i am specifically looking to create this in kibana maps)
