Rebalancing Data Using Management Console

Vertica can rebalance the database when you add or remove nodes. If you notice data skew where one node shows more activity than another (for example, most queries processing data on a single node), you can manually rebalance the database using MC if that database is imported into the MC interface.

On the Manage page, click Rebalance in the toolbar to initiate the rebalance operation.

During a rebalance, you cannot perform any other activities on the database cluster, such as start, stop, add, or remove nodes.
