Local SSDs are available through both "SCSI" and "NVMe" interfaces.
If not indicated, "NVMe" will be the default one for local ssds.
We only support "SCSI" for persistent disks now.

Name of a public or custom image used as the data source.
For example, the following are all valid URLs:
Specify the image by its family name:
projects/{project}/global/images/family/{image_family}
Specify the image version:
projects/{project}/global/images/{image_version}
You can also use Batch customized image in short names.
The following image values are supported for a boot disk:
"batch-debian": use Batch Debian images.
"batch-centos": use Batch CentOS images.
"batch-cos": use Batch Container-Optimized images.

Disk size in GB.
For persistent disk, this field is ignored if data_source is image or
snapshot.
For local SSD, size_gb should be a multiple of 375GB,
otherwise, the final size will be the next greater multiple of 375 GB.
For boot disk, Batch will calculate the boot disk size based on source
image and task requirements if you do not speicify the size.
If both this field and the boot_disk_mib field in task spec's
compute_resource are defined, Batch will only honor this field.
Disk type as shown in gcloud compute disk-types list.
For example, local SSD uses type "local-ssd".
Persistent disks and boot disks use "pd-balanced", "pd-extreme", "pd-ssd"
or "pd-standard".
