I'm build a test cluster and was given basically the following...
3 Master Nodes
4 Data Nodes
A couple Client Nodes
A couple Ingestion nodes
My question is...
The setting for number of shards, is that setting set in the config for any node that holds data, or should that be set for all nodes regardless of role.
Our data Nodes are attached to 30+ TB storage drives per node ( there will be ALOT of data ingested (read-only). How many shards per node would be generally rule of thumb "good"?
Same as 2 but with replica sets?
Thx for any insight you all could provide
