public class AdminAddRanksRequest extends Object implements org.apache.avro.generic.IndexedRecord
GPUdb.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
GPUdb.adminRebalance
.
The database must be offline for this operation, see GPUdb.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:
* 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
GPUdb.createJob
.

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
GPUdb.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 configParams
.configParams
- 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 configParams
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 configParams
array
will result in the new ranks being set with default
parameters.options
- Optional parameters.
DRY_RUN
: If TRUE
, only validation checks will
be performed. No ranks are added.
Supported values:
The default value is FALSE
