# GetMLTaskRuns
<a name="API_GetMLTaskRuns"></a>

Gets a list of runs for a machine learning transform. Machine learning task runs are asynchronous tasks that AWS Glue runs on your behalf as part of various machine learning workflows. You can get a sortable, filterable list of machine learning task runs by calling `GetMLTaskRuns` with their parent transform's `TransformID` and other optional parameters as documented in this section.

This operation returns a list of historic runs and must be paginated.
