HeLifu commented on KUDU-2823:
------------------------------
Thanks to Grant and Alexey.
To Alexey: I added some new tablet servers to the cluster before adding new
partition the day before yesterday, so the skew that i pasted in front was a
little bit bigger; then i rebalanced the whole cluster yesterday, it took a
long time and now the skew becomes small(6). So the placement policy for adding
partitions is not bad. I'm sorry to have misled you.

>
> 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.
