Hello,

I am loading data from database into elasticsearch using logstash ,

during loading, does Elastic Search allows us to create Trigger-like functionality with our own rules to create new fields?  
Ex:-  
can we add new fields dynamically to calculate the sum of 2 fields(x & y) and create a new field(z) to append the value(z = x + y) while loading.

Yes, I think what you are looking for is ingest functionality:
