I am using Logstash to read JSON data and load it to ElasticSearch. I am using a combination of update with doc_as_upsert to update existing documents and insert new. The specific application need is that in Elastic there should be no empty fields. So the field should be deleted from a document rat…

An http filter can POST into elasticsearch.

Remove fields from documents based on their value

In the past I have used logstash to generate a text file that I curled into elasticsearch, but it could probably be done using an http filter. You do not have to have an output in a logstash pipeline.
