I know this has been discussed already on previous threads, though our use-case might be a bit specific. We have a product import process that runs on a daily basis and saves a bunch of products into an ES index (~5M items). Every day some new products are coming in, but 99% of them are just existing products being updated. One requirement that we have is that we need to keep track of when a product was first imported. So far we are handling it by doing a **scripted upsert** : if the product already exists then don't touch the createdAt field otherwise populate it. So this works but it turns out that the scripted upsert method is actually about 5 times slower then a normal doc as upsert method according to the metrics I get from xpack monitoring. Unfortunately, ES does not support indexing time timestamp creation natively anymore, but is using a script to handle this the only option that we have, and if so does it mean we are stuck with a slow indexing rate while doing so? I've tried every [indexing speed tuning recommendations](https://www.elastic.co/guide/en/elasticsearch/reference/current/tune-for-indexing-speed.html) with no success. ---
