we have 1 coordinating-node 1 master-node 5 data-nodes and 1 kibana.
we are planning to scale it up to 2 coordinating-nodes 3 master-node 30 data-nodes 2 kibana.
Only coodrinating node is esposed to kibana and logstash (master-node , Data-nodes are not expose all the request are processed by coordinating node)
Please suggest on following questions:
Is it possible to have multiple masters?
How does mutli-master setup work is it something like active passive kind of setup ? will one master-node be leader and other 2 are in standby ?
Can i have 2 coordinating nodes ?
How can we maintain HA for logstash
