Search Latency when adding a Node or when a Node goes down

Hello Folks,
I am new to ElasticSearch and exploring for use in our Electronic
Products.
Approximately 60 million documents from 10-12 sources, ~100 fields and ~QPS
of 50.
Please share any information on impacts to search/indexing latency when a
Node is added or goes down for any reason.

regards,
girish

General Q, general A :slight_smile:

  • Fewer nodes -> slower queries
  • Node down -> insufficient replicas -> shard shuffling -> disk + network
    IO -> slower queries
