currently i use elasticsearch.json to set the global shard and replica
setting.
I have two indices and they have different total index size, e.g. 1T
vs 5T, so i need to set them with different shard and replica setting,
where should i put my configuration instead of sending a url post when
create the index

It is not possible to change the shard count after index creation. So
you'll need to set it when creating the index.
