#max_capacityFloat

The number of Glue data processing units (DPUs) that are allocated to task runs for this transform. You can allocate from 2 to 100 DPUs; the default is 10. A DPU is a relative measure of processing power that consists of 4 vCPUs of compute capacity and 16 GB of memory. For more information, see the Glue pricing page.

MaxCapacity is a mutually exclusive option with NumberOfWorkers and WorkerType.

  • If either NumberOfWorkers or WorkerType is set, then MaxCapacity cannot be set.

  • If MaxCapacity is set then neither NumberOfWorkers or WorkerType can be set.

  • If WorkerType is set, then NumberOfWorkers is required (and vice versa).

  • MaxCapacity and NumberOfWorkers must both be at least 1.

When the WorkerType field is set to a value other than Standard, the MaxCapacity field is set automatically and becomes read-only.

Returns:

  • (Float)

#worker_typeString

The type of predefined worker that is allocated when a task of this transform runs. Accepts a value of Standard, G.1X, or G.2X.

  • For the Standard worker type, each worker provides 4 vCPU, 16 GB of memory and a 50GB disk, and 2 executors per worker.

  • For the G.1X worker type, each worker provides 4 vCPU, 16 GB of memory and a 64GB disk, and 1 executor per worker.

  • For the G.2X worker type, each worker provides 8 vCPU, 32 GB of memory and a 128GB disk, and 1 executor per worker.

MaxCapacity is a mutually exclusive option with NumberOfWorkers and WorkerType.

  • If either NumberOfWorkers or WorkerType is set, then MaxCapacity cannot be set.

  • If MaxCapacity is set then neither NumberOfWorkers or WorkerType can be set.

  • If WorkerType is set, then NumberOfWorkers is required (and vice versa).

  • MaxCapacity and NumberOfWorkers must both be at least 1.

Returns:

  • (String)
