How to insert document to an index in elasticsearch without specifying document id using java apis?

Question

I'm new to Elastic search and I'm doing a task in which I need to upload more number of documents to ES. Whenever I upload everytime, I need to specify document id for that document in IndexRequest api. Is there any way in java so that i can insert documents without giving id for it (i.e creating random document id's for my documents).

Are you using some kind of framework (spring data for example) or the elastic rest client directly? — ibexit, Jul 05 '21 at 09:56
@ibexit I'm using servlets for elastic high level rest clients — Ajay Venkatesh, Jul 05 '21 at 09:59

Please have a look at https://www.elastic.co/guide/en/elasticsearch/client/java-rest/7.13/java-rest-high-document-index.html

In order to have the id autogenerated, just ommit this call:

request.id("1");

This should do the trick for single document operations.

If you need bulk changes, see https://www.elastic.co/guide/en/elasticsearch/client/java-rest/master/java-rest-high-document-bulk.html

In this case, also remove the .id("1") method call.
