Hi,
Question#1:
How to manually select tokens to force equal spacing
What is the correct procedure for data re-partitioning?
Suppose I have 3 nodes - A, B, C
tokens on the ring:
A: 0
B: 2.8356863910078205288614550619314e+37
C: 5.6713727820156410577229101238628e+37
Then I add node D, token: 1.4178431955039102644307275309655e+37 (B/2)
Start node D with -b
Wait
Run
I see, so to make cluster always balanced (data-wise) number of nodes should
be doubled each time.
I see some activity in JIAR regarding load-balancing for v.0.5
Does it target the same thing? transferring data from node to node and
appropriately modifying tokens?
