Question on adding new node to ES cluster

Elastic Stack Elasticsearch
1

Hi,

I am trying to understand the process of adding a new node to an existing
ES cluster. Specifically I wanted to understand during the shard allocation
that happens as a part of adding a new node, will the cluster overall be
available for serving new requests - specifically search requests ? Or can
we expect any performance impacts during the same ?

Thanks,
Karthik

Elasticsearch will be able to serve all your requests during that time.

You will probably see some IO increasing but IIRC it will be bounded to 20 mb/s by default.
