  • Enum Constant Details

    • Idle

      public static final KafkaAutoRebalanceState Idle
      Initial state with a new auto-rebalancing initiated when scaling down/up operations were requested. This is also the ending state after an auto-rebalancing completed successfully or failed. Transitions to:
      RebalanceOnScaleDown
      if a scale down operation was requested. This transition happens even if a scale up was requested at the same time but the rebalancing on scaling down has the precedence. The rebalancing on scale up is queued. They will run sequentially.
      RebalanceOnScaleUp
      if only a scale up operation was requested. There was no scale down operation requested.

    • RebalanceOnScaleDown

      public static final KafkaAutoRebalanceState RebalanceOnScaleDown
      A rebalancing related to a scale down operation is running. Transitions to:
      RebalanceOnScaleDown
      if a rebalancing on scale down is still running or another one was requested while the first one ended.
      RebalanceOnScaleUp
      if a scale down operation was requested together with a scale up and, because they run sequentially, the rebalance on scale down had the precedence, was executed first and completed successfully. We can now move on with rebalancing for the scale up.
      Idle
      if only a scale down operation was requested, it was executed and completed successfully or failed.

    • RebalanceOnScaleUp

      public static final KafkaAutoRebalanceState RebalanceOnScaleUp
      A rebalancing related to a scale up operation is running. Transitions to:
      RebalanceOnScaleUp
      if a rebalancing on scale up is still running or another one was requested while the first one ended.
      RebalanceOnScaleDown
      if a scale down operation was requested, so the current rebalancing scale up is stopped (and queued) and a new rebalancing scale down is started. The rebalancing scale up will be postponed.
      Idle
      if a scale up operation was requested, it was executed and completed successfully or failed.
