Rebalancing data using Management Console

Vertica can rebalance your subcluster 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 sublcluster using MC if the database is imported into the MC interface.

On the Management Console Manage page in the Subclusters tab, click Rebalance above the subcluster to initiate the rebalance operation.

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