-* You can update the `analysis_limits` only while the job is closed.
-* The `model_memory_limit` property value cannot be decreased below the current usage.
 * If the `memory_status` property in the `model_size_stats` object has a value
 of `hard_limit`, this means that it was unable to process some data. You might
 want to re-run this job with an increased `model_memory_limit`.

-`description`::
-  (string) The new description for the detector.
-
-`custom_rules`::
-  (array) The new list of <<ml-detector-custom-rule, rules>> for the detector.
