Hello! My name is Hoang. I'm a newbie. I doing a project and use ElasticSearch. In Cluster, these are three nodes. I config, each shard is (3 primary shard and 2 replica). Now, I want to add a new node to Cluster.
- How ElasticSearch allocate will allocate shards (Primary Shards + Replica Shards)?
- Do I need to change the number of shards? (Example: 4 nodes => (4 Primary Shards + ....))
Thank you so much!
