We are having 5 node in our cluster with 2 groups for rack awareness. With 2 nodes in group a and 3 nodes in group b.
We have 4 nodes with data service and 1 node with index& query service . As of now we are not using views . While creating a new bucket we are planning to use Views .
Do we need to have 2 index service nodes for making it a HA configuration as we have only one for the index service and if it fails what will be the impact on the View which were been created.
As i understand MapReduce views are stored on the disk and The data service is responsible to handle MapReduce views referring to the below document.
Please suggest we are using couchbase 5.1 version
