Currently I am working on a single node Elasticsearch setup. But the replication factor was set to 1 by default. The space on my node is 3TB. If I decrease the replication factor to 0 , what will happen in that case?
- On the current node since replication factor is 1 , does this create 2 replicas?
- What will happen to the already consumed space on this node, will that be decreased or will it not impact?
- Once I move to production, should I move replication factor back to 1 or this will only be required if another node is added.
Basically I want to understand the concept of changing the replication factor on the space consumed on the node.
