#of shards per index by keeping the future growth of cluster in mind?

Elastic Stack Elasticsearch

I am looking for feedback of my conclusion. I observed number of articles
and discussions about defining number of shards per index.

*. By default Es is providing 5 shards and 1 replica for each index. I
believe, There is no particular formula to define number of shards per
index. It depends on the type of the data you are going to index in shards.
*. #of nodes >= #of shards * (#of replicas + 1) for each index.
*. For stats type of data. It is good to have 1 shards and 1 replica.
Because such type of data suppose to have so many documents but smaller
size and most probably having numbers only.

Thank you.

You do want to have more shards than nodes, so you can scale out easily. As
for stats type of data, a single shard assumption is not really relevant,
even small documents can amount to a lot of data.
