I have 3 nodes elastic cluster each node assigned with 1Tb hard disk, 15GB Ram and 4 CPU
Elastic version using is 6.3.0.
At the moment I have 3,304,624,313 documents using 2.1 TB disk space
This data is collected within a month.
Doing a search on cluster takes over 5 minutes.
In order to optimize search performance, what can I do?
what is the maximum data size 3 node cluster can handle?
Is it ok to split the indices vertically so small fields are grouped in one index? will it help improving performance
