## Required authorization

* Index privileges: `read`,`create_index`,`manage`,`index`,`view_index_metadata`
* Cluster privileges: `manage_ml`



## Servers
- http://api.example.com: http://api.example.com ()


## Authentication methods

## Parameters

#### Path parameters
- **id** (string)
  Identifier for the data frame analytics job. This identifier can contain
lowercase alphanumeric characters (a-z and 0-9), hyphens, and
underscores. It must start and end with alphanumeric characters.


## Body parameters
Content-type: application/json

- **description** (string)
  A description of the job.
- **model_memory_limit** (string)
  The approximate maximum amount of memory resources that are permitted for
analytical processing. If your `elasticsearch.yml` file contains an
`xpack.ml.max_model_memory_limit` setting, an error occurs when you try
to create data frame analytics jobs that have `model_memory_limit` values
greater than that setting.
- **max_num_threads** (number)
  The maximum number of threads to be used by the analysis. Using more
threads may decrease the time necessary to complete the analysis at the
cost of using more CPU. Note that the process may use additional threads
for operational functionality other than the analysis itself.
- **allow_lazy_start** (boolean)
  Specifies whether this job can start when there is insufficient machine
learning node capacity for it to be immediately assigned to a node.
