How to improve Rebalance_cluster() performance
During our Vertica cluster expansion, we see that the Rebalance_cluster() operation takes un-calculated time and i guess, you might also have experienced the same.
Is there any method or temporary settings in vertica to improve rebalance operation ?
In my setup, we have a 3-node cluster and trying to add 1 more cluster. There are segmented projection where small projections was very quickly rebalanced but big projections are problematic.
when i try to rebalance a projection of 400GB, it is giving us speed of 20% seperation_percentage per hour and overall task takes about 6 hours. Any method to pump-up this operation to save time?
