TaskResourceRequest(resourceName: str, amount: float)¶
A task resource request. This is used in conjunction with the
pyspark.resource.ResourceProfileto programmatically specify the resources needed for an RDD that will be applied at the stage level. The amount is specified as a float to allow for saying you want more than 1 task per resource. Valid values are less than or equal to 0.5 or whole numbers. Use
pyspark.resource.TaskResourceRequestsclass as a convenience API.
Name of the resource
Amount requesting as a float to support fractional resource requests. Valid values are less than or equal to 0.5 or whole numbers. This essentially lets you configure X number of tasks to run on a single resource, ie amount equals 0.5 translates into 2 tasks per resource address.
