|
|
|

//===== Description
|
|
|
|

|
|
<<ml-apilimits,analysis limits>>.
|
|
|
|

|
(time units) Advanced configuration option. The time between each periodic
|
|
persistence of the model. See <<ml-job-resource>>.

|
|
(string) The name of the index in which to store the {ml} results. The default
|
|
