Ingest Node Elasticsearch While pushing data from MySQL to Elasticsearch using logstash - sql

Question

I am a windows Developer recently exploring elasticsearch. I was wondering if there is a way to bind a field to another one such that the values of the binding field are entered into the binded field.
For Example: In windows development: I can bind the value of a
textblock to a string property and when I populate the string
property, the textblock text automatically gets updated. Similar in
MS Excel, I can put the value of one cell into another by simply
binding it.
What Exactly Am I doing
I am using elasticsearch to hold location data. now I have a latitude field and a longitude field. I have another field geo_location of type geo_point.
What I want to achieve
I want that each time i push some data into the index that has a latitude and longitude(it'll always have latitude and longitude), the geo_location field gets populated automatically from the newly pushed data's latitude and longitude.
Is that even possible? If yes then can anyone tell me how? or tell me what is this process called so that I can look up a documentation on it.
The logstash.config file has the below code for output {} to push data to elasticsearch index.
elasticsearch
{
index => "mytestproject_locationbase"
document_type => "uap"
hosts => "localhost:9200"
}
How do I tweak the output code to not delete the existing index and then pre-process latitude and longitude fields to put into a geo_point type field

Answer 1

This is possible using a pipeline. You can create a pipeline that moves a field either around or copies it (or removes it), thus you can create the required JSON structure to store a geo point.
