Hi,
I am trying to index an initial workload of ~1 billion documents into ES 5.2. The documents are pulled from an MYSQL database and they already contain a unique ID and I want to use the same IDs in ES for a quick reference.
I was reading about how to tune indexing and I have tried disabling index refresh and replicas and it sped up the process so now I am wondering if there is a way to disable ID lookup as it might speed up things more.
So is there a way to do this?
Regards
