I have server with two SSD and two HDD disks. What is the best way to install and run Elasticsearch on this server to get the lowest index and search time. Is it possible to index documents on SSD disks first and move them to HDD lazy mode or something like this to get better timing in index phase? What is the best solution to get low time in searching?
In order to control which data resined on which type of disk you will need to set up two separate data nodes - one backed by SSD and one backed by HDD. How you organise your data will depend on the use-case, but for logging and metrics use-cases this is often referred to as a hot-warm architecture.
