  -* 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`.
