Elasticsearch update document without creating new index

Question

I have many existing indices partition by date. Eg: index_190901, index_190902,...

And I have an API which takes index_name and doc_id as inputs. User want to update some documents in index by input fields, index_name, doc_id.

I'm trying to update document using the following code:

        updateRequest.index("invalid_daily_index")
          .type("type")
          .id("id")
          .doc(jsonMap)

It works fine if user input existing index but if user input non-existing index, new index with no document will be created.

I know that I can setup auto_create_index but I still want to create index automatically when I insert new documents.

Check if index is existed with client.indices.exists(request, RequestOptions.DEFAULT) is quite expensive. I don't want to check it every request

How to make Elasticsearch to not create new index when I use updateRequest.

Answer 1

You can block the option to automaticaly create non existing indices by putting false to the action.auto_create_index setting of the cluster

PUT _cluster/settings
{
    "persistent" : { "action.auto_create_index” : "false" }
}
