Detailed Description
A set of parameters for Kinetica.adminAddRanks.
Add one or more ranks to an existing Kinetica cluster. The new ranks will not contain any data initially (other than replicated tables) and will not be assigned any shards. To rebalance data and shards across the cluster, use Kinetica.adminRebalance.
The database must be offline for this operation, see Kinetica.adminOffline
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:
* AdminAddRanksRequest.hosts would be an array including 172.123.45.67 in the first two indices (signifying two ranks being added to host 172.123.45.67) and 172.123.45.68 in the last index (signifying one rank being added to host 172.123.45.67)
* AdminAddRanksRequest.config_params would be an array of maps, with each map corresponding to the ranks being added in AdminAddRanksRequest.hosts. The key of each map would be the configuration parameter name and the value would be the parameter’s value, e.g. ‘“rank.gpu”:“1“‘
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 Kinetica.createJob.

Constructor & Destructor Documentation
◆ AdminAddRanksRequest() [1/4]
| inline |
Constructs an AdminAddRanksRequest object with default parameters.
Definition at line 150 of file AdminAddRanks.cs.
◆ AdminAddRanksRequest() [2/4]
| inline |
Constructs an AdminAddRanksRequest object with the specified parameters.
| hosts | Array of host IP addresses (matching a hostN.address from the gpudb.conf file), or host identifiers (e.g. ‘host0’ from the gpudb.conf file), on which to add ranks to the cluster. The hosts must already be in the cluster. If needed beforehand, to add a new host to the cluster use Kinetica.adminAddHost. Include the same entry as many times as there are ranks to add to the cluster, e.g., if two ranks on host 172.123.45.67 should be added, hosts could look like ’[“172.123.45.67”, “172.123.45.67”]’. All ranks will be added simultaneously, i.e. they’re not added in the order of this array. Each entry in this array corresponds to the entry at the same index in the config_params . |
| config_params | Array of maps containing configuration parameters to apply to the new ranks found in hosts . For example, ‘“rank.gpu”:“2”, “tier.ram.rank.limit”:“10000000000”’. Currently, the available parameters are rank-specific parameters in the Network, Hardware, Text Search, and RAM Tiered Storage sections in the gpudb.conf file, with the key exception of the ‘rankN.host’ settings in the Network section that will be determined by hosts instead. Though many of these configuration parameters typically are affixed with ‘rankN’ in the gpudb.conf file (where N is the rank number), the ‘N’ should be omitted in config_params as the new rank number(s) are not allocated until the ranks have been added to the cluster. Each entry in this array corresponds to the entry at the same index in the hosts . This array must either be completely empty or have the same number of elements as the hosts . An empty config_params array will result in the new ranks being set with default parameters. |

Property Documentation
◆ config_params
| getset |
Array of maps containing configuration parameters to apply to the new ranks found in AdminAddRanksRequest.hosts.
For example, ‘“rank.gpu”:“2”, “tier.ram.rank.limit”:“10000000000”’. Currently, the available parameters are rank-specific parameters in the Network, Hardware, Text Search, and RAM Tiered Storage sections in the gpudb.conf file, with the key exception of the ‘rankN.host’ settings in the Network section that will be determined by AdminAddRanksRequest.hosts instead.

Each entry in this array corresponds to the entry at the same index in the AdminAddRanksRequest.hosts. This array must either be completely empty or have the same number of elements as the AdminAddRanksRequest.hosts. An empty AdminAddRanksRequest.config_params array will result in the new ranks being set with default parameters.

◆ hosts
| getset |
Array of host IP addresses (matching a hostN.address from the gpudb.conf file), or host identifiers (e.g.
‘host0’ from the gpudb.conf file), on which to add ranks to the cluster.
The hosts must already be in the cluster. If needed beforehand, to add a new host to the cluster use Kinetica.adminAddHost. Include the same entry as many times as there are ranks to add to the cluster, e.g., if two ranks on host 172.123.45.67 should be added, AdminAddRanksRequest.hosts could look like ’[“172.123.45.67”, “172.123.45.67”]’.

Each entry in this array corresponds to the entry at the same index in the AdminAddRanksRequest.config_params.
