[jira] [Updated] (KUDU-2823) Rebalance range partition
[ https://issues.apache.org/jira/browse/KUDU-2823?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
HeLifu updated KUDU-2823:
-------------------------
Description: 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 impact the disk and network. So, I think it will be good to rebalance the new added range partitions.
