> I’m planning to add a new node to a cluster with the following setup:  
> • 5 nodes, each holding 500GB of data  
> • RF is 3  
> Is there any benchmark or reference data on how long it typically takes to add a new node under these conditions?

The new tablet code, in the source available version - 2024.2 will do it in 15 minutes
