What happens when a new node is added to the ES cluster?


(Atharva Patel) #1

I am curious to know what exactly happens when a new node is added in the
existing running ES cluster.

  • How do the primary and replica shards get rearranged (in general the
    storage-data distribution)?
  • What happens to the query and index processing load?
  • What are the other factors that get affected in terms of performance
    improvement or decrement when adding a new node?
