How many elastic search shards should I have for a physical node?

Elastic Stack Elasticsearch
1

There are many variables here like the number of documents, the size of
documents.
What I want to understand though, is that what are the downsides of having
of too many shards for a physical node?

Each shard is a Lucene instance.
It uses memory, file descriptors, CPU, IO...

You should keep its number per node small.

If you are a RDBMS user, you probably limit the number of databases you manage on a single physical machine, right?
