Speed up reindex


(Nayun Oh) #1

I need to reindex a large index as a backup. But It takes a lot of time.
one minute per 2 giga bytes. I have set indices.index buffer size to 70% in elasticsearch.yml and refresh interval to -1. Can you give me some advice?

Increase the resources to your cluster - memory, cpu, use SSDs.
