      AdminSwitchoverRequest

      public AdminSwitchoverRequest()
      Constructs an AdminSwitchoverRequest object with default parameters.

      AdminSwitchoverRequest

      public AdminSwitchoverRequest(List<String> processes, List<String> destinations, Map<String,String> options)
      Constructs an AdminSwitchoverRequest object with the specified parameters.
      Parameters:
      processes - Indicates the process identifier to switch over to another host. Options are ‘hostN’ and ‘rankN’ where ‘N’ corresponds to the number associated with a host or rank in the Network section of the gpudb.conf file; e.g., ‘host[N].address’ or ‘rank[N].host’. If ‘hostN’ is provided, all processes on that host will be moved to another host. Each entry in this array will be switched over to the corresponding host entry at the same index in destinations.
      destinations - Indicates to which host to switch over each corresponding process given in processes. Each index must be specified as ‘hostN’ where ‘N’ corresponds to the number associated with a host or rank in the Network section of the gpudb.conf file; e.g., ‘host[N].address’. Each entry in this array will receive the corresponding process entry at the same index in processes.
      options - Optional parameters.
      • DRY_RUN: If set to TRUE, only validation checks will be performed. Nothing is switched over. Supported values:The default value is FALSE.
      The default value is an empty Map.

      getProcesses

      public List<String> getProcesses()
      Indicates the process identifier to switch over to another host. Options are ‘hostN’ and ‘rankN’ where ‘N’ corresponds to the number associated with a host or rank in the Network section of the gpudb.conf file; e.g., ‘host[N].address’ or ‘rank[N].host’.
