Detailed Description

A set of output 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:

• 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)

• configParams would be an array of maps, with each map corresponding to the ranks being added in 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 const.
