Configuring the batch size

To configure the batch size, we will explore how to determine the batch size in Azure Batch. Batch size refers to both the size of Batch pools and the size of the VMs in those pools. The following guidelines are generic enough that they can be applied to other services such as Spark and Hive too.

Here are some of the points to consider while deciding on the batch size:

• Application requirements: Based on whether the application is CPU-intensive, memory-intensive, storage-intensive, or network-intensive, you will have to choose the right types of VMs and the right sizes. You can find all the supported VM sizes using the following Azure CLI command (here, centralus is an example):

  az batch location list-skus –location centralus

• Data profile: If you know how your input data is spread, it will help in deciding the VM sizes that will be required. We will have to plan for the highest amount of data that will be processed by each of the VMs.
