Suppose we have some indices in our cluster. I can make a snapshot of my favorite index and I can restore the same index again to my cluster if the same index is not exists or is closed. But what if the index currently exists and I need to add/append extra data/documents to it ?
Suppose I currently have 100000 documents in my index in my server. I create/add 100 documents to my index in my local system which has the same name, the same mappings and the same settings, the same number of shards and . . ., now I want to add 100 documents to my current index in my server (100000 documents) . What is the best way ?
In MySQL I use export to csv or excel and ... and it is so easy to import or append data to currently existed index.
