Alexey Serbin commented on KUDU-2823:
-------------------------------------
[~helifu] thank you for the snippet of the 'tablet replica distribution', it
looks interesting.
Do I understand correctly that it was just the result of just adding partitions
to the table? I.e. no tablet server downtime, now new tablet servers added
into the cluster, etc.? If that the case, then maybe there is a bug somewhere
in the code, so upon adding partitions the placement policy doesn't apply for
some reason, and we need to address that.

> Right now we will add new range every day for a fact table which has
> range+hash partitions, and then rebalance it as soon as possible. It seems
> that not only the new added tablets of this table but also the historical
> tablets will be rebalanced. But the historical tablets already have data, so
> they are heavy to move and it will increase the disk and network suddenly.
> So, I think it will be good to rebalance the new added range partitions.
