Rebalancing using the GUI
Rebalance option is available on the Nimbus UI where you can choose the topology that is
to be rebalanced, and then use the option from the GUI. The topology drains as per the spe-

the ones in the internal queues are processed and once completely clear, the workers and
tasks are redistributed. The user also has option to increase or decrease the parallelism for
various bolts and spouts using the rebalance options. The following screenshot describes
