I have a request to search through 200 closed indexes for some data. Our current cluster is running well but at the edge of what it can handle. I don't want to open all the necessary indexes at one time to avoid overloading the cluster.
I like to open the index, search it, collect data and close it back down. I understand I will hit the system with a good amount of overhead doing this.
Is there a better way to do this?
The cluster is a 5.6.16 version and is due for upgrades latter this year. It is currently at this version while software that relies on it is upgraded to handle the newer Elasticsearch versions.
