My requirement is to do the horizontal expansion of Elasticsearch.
Now I have two nodes and have created some indexes but the capacity is not enough.
I found that after a new node were added into cluster, the shards that originally on the old two nodes were reassigned until all three nodes were distributed with shards.
when the amount of data is large, the time to wait for redistribution is too long.
Here is my question:
1.Is there any way to not change the distribution location of the original old data? After the node is added, only the new index will be allocated on the existing three nodes.
Urge for help! Thanks a lot!
