A new balancer is a plug-in class that instructs the Master process where

One strategy to deal with imbalanced data is to add a random partition
prefix to your row Ids.

Thanks Eric,
Just to make sure I’m going in the right direction, this would involve
extending the TabletBalancer class, correct? How do I add it to the table after
that (and remove the old
