Command-Line Interface (CLI)
Pinot provides a rich CLI to perform almost every operation on the cluster. You can execute all the commands using the pinot-admin.sh. The script is located in the bin/ directory of the Pinot binary distribution or /opt/pinot/bin in docker container.

Rebalance Table
Rebalance a table i.e. reassign instances and segments for a table in the cluster.
For segment reassignment, the following modes are offered:
With-downtime rebalance: the IdealState is replaced with the target segment assignment in one go and there are no guarantees around replica availability. This mode returns immediately without waiting for ExternalView to reach the target segment assignment. Disabled tables will always be rebalanced with downtime.No-downtime rebalance: care is taken to ensure that the configured number of replicas of any segment are available (ONLINE or CONSUMING) at all times. This mode returns after ExternalView reaching the target segment assignment. In the edge case scenarios mentioned later, ifbest-effortsis disabled, rebalancer will fail the rebalance because the no-downtime contract cannot be achieved, and table might end up in a middle stage. User needs to check the rebalance result, solve the issue, and run the rebalance again if necessary. Ifbest-effortsis enabled, rebalancer will log a warning and continue the rebalance, but the no-downtime contract will not be guaranteed. Downtime can occur in the following edge case scenarios -Segment falls into ERROR state in ExternalView -> with best-efforts, count ERROR state as good state.
ExternalView has not converged within the maximum wait time -> with best-efforts, continue to the next stage
If the controller that handles the rebalance goes down/restarted, the rebalance isn't automatically resumed by other controllers
