I have a cluster of 3 nodes. When I add 1 new node to the cluster, the rebalance
speed is slow, the details are:
- crdb V2.0.2
- 3 nodes with 100,000,000 rows, about 1900 ranges
- add node 4
- it takes 10 hours when all 4 nodes is balanced
How can I speed up this rebalance?
When all 4 nodes balanced, I killed node 4 to test
the rebalance speed of shrinking cluster. It takes
about 1 hour.
Why rebalance of shrinking is much faster?
