Shard per index on non-clustered elasticsearch instance

Elastic Stack Elasticsearch
1

Hello everyone,
Will it matter configuring some 'x' number of shards per index, if I am
using single instance/node of elastic search.
I have a single box that has elastic search instance on it (no cluster).
Will it have any implications, when using default 5 (or maybe just 1)
shards per index?
Creating an index with more number of shards without a cluster or more node
will help in anyway in terms of performance or scalability?

Please advise.
Appreciate your inputs!

Regards,
Sagar Shah

Not unless you are creating a lot of indies on that node, remember that a
shard is a lucene instance and take up a certain amount of resources.

Generally it's a good idea to create multiple shards if you expect to add
more nodes, that way it's easier to spread the data across the new nodes
without having to reindex. But for dev purposes on a single node, having a
single shard index is fine.

Appreciate your input Mark.
So my understanding was correct, that on a single node (without cluster)
having single shard per index will work almost the same as having default 5
shards per index.

Too many people think more of security instead of opportunity. They seem
more afraid of life than death!!!
