Description

Description

The AzureBatchOperator currently has no option to set it to deferrable, which would allow the task to be run by an async low-resource worker ("triggerer"). Therefore Azure Batch tasks block a regular worker, even though they only ping the Azure platform from time to time.

I propose to add this parameter and changing the operator to use asynchronous calls.

As a reference, the AWS Batch operator has a parameter deferrable.

Use case/motivation

Adding this parameter and changing the operator to use asynchronous calls would reduce resource consumption when using Azure Batch.

Research direction
Review the current implementation of `AzureBatchOperator` in the Airflow source code, likely located in the `airflow/providers/azure/transfers/` directory. Study the AWS Batch operator's implementation of the `deferrable` parameter and its use of async calls. Examine the triggerer architecture in Airflow documentation. Ensure that adding deferrable support does not break existing synchronous usage.
