We are monitoring the internet and we have aggregated a large base of
documents. We currently have 1 165 908 189 documents, which we want to
emigrate to elasticsearch, and we would like to ask you a few questions.
The question concerns the drives for elasticsearch. The system uses the
SSD, however they are four times more expensive than HDD.
Which solution would you recommend to use: SSDs and one reply for the
shard, or HDD
and 3 replicas of the shard?
