A set of input parameters for const.
Add one or more new ranks to the Kinetica cluster. The new ranks will not contain any data initially, other than replicated tables, and not be assigned any shards. To rebalance data across the cluster, which includes shifting some shard key assignments to newly added ranks, see const.
For example, if attempting to add three new ranks (two ranks on host 172.123.45.67 and one rank on host 172.123.45.68) to a Kinetica cluster with additional configuration parameters:
This endpoint's processing includes copying all replicated table data to the new rank(s) and therefore could take a long time. The API call may time out if run directly. It is recommended to run this endpoint asynchronously via const.

Constructs an AdminAddRanksRequest object with the specified parameters.
[in] | hosts_ | The IP address of each rank being added to the cluster. Insert one entry per rank, even if they are on the same host. The order of the hosts in the array only matters as it relates to the configParams. |
[in] | configParams_ | Configuration parameters to apply to the new ranks, e.g., which GPU to use. Configuration parameters that start with 'rankN.', where N is the rank number, should omit the N, as the new rank number(s) are not allocated until the ranks are created. Each entry in this array corresponds to the entry at the same array index in the hosts. This array must either be completely empty or have the same number of elements as the hosts array. An empty array will result in the new ranks being set only with default parameters. |
[in] | options_ | Optional parameters.
