Multiple shard VS multiple indexing

Elastic Stack Elasticsearch

Hi ,

If i have a huge database and i want to improve performance , either i can

  • Increase number of shards
  • Partition a single index logically (say one index will hold a year's
    data) and restrict the search to the required index only. I agree we get
    some mileage here as we are restricting the search to the required index
    only.

Is there any other advantages for multiple index over multiple shards here ?

Thanks
Vineeth

I would prefer multiple indices as it can grow dynamically without
reindexing.
When using multiple shards and you want to increase the number of
shards you'll need to reindex the whole index.
