FlexibleInstanceGroupConfig(mapping=None, *, ignore_unknown_fields=False, **kwargs)

The configuration for High Obtainability (HO) flexible instance groups. Flexible instance group configs serve as the single source of truth for desired state.

Attributes
Name	Description
num_instances	int Optional. The number of VM instances requested. For master instances, this must be 1. For worker and secondary worker instances, this represents the desired capacity of the group and is mutable via cluster update operations and autoscaling.
core_count	int Optional. The number of vCPUs per instance. Must be a power of 2 (2, 4, 8, 16, 32). This is a create-time specification and is not currently mutable via update masks.
boot_disk_size_gb	int Optional. The boot disk size in GB. This is a create-time specification and is not currently mutable via update masks.
hardware_class	google.cloud.dataproc_v1.types.FlexibleInstanceGroupConfig.HardwareClass Optional. The hardware class of the instances. This is a create-time specification and is not currently mutable via update masks.

Classes

HardwareClass

HardwareClass(value)

Controls the hardware class for the flexible instance group.

    Candidate machine types include `n4-standard`,
    `n4d-standard`, `n2-standard`, and `n2d-standard`
    (Rank 0), and `c4-standard` and `c4d-standard` (Rank 1)
    (for requested core counts 2, 4, 8, 16, 32).

    Warning: The specific machine families and types selected
    for this hardware class are subject to change. Users should
    not take a dependency on the underlying machine type
    selection.
PERFORMANCE (2):
    Performance hardware class. Provides a high-performance
    configuration with approximately 8GB of memory per vCPU
    (e.g. high-memory machine types) and higher-tier disk
    configurations (e.g. higher IOPS and throughput).

    Candidate machine types include `n4-highmem`,
    `n4d-highmem`, `n2-highmem`, and `n2d-highmem` (Rank
    0), and `c4-highmem` and `c4d-highmem` (Rank 1) (for
    requested core counts 2, 4, 8, 16, 32). `n4`, `n4d`,
    `c4`, and `c4d` use Hyperdisk Balanced with provisioned
    storage, whereas `n2` and `n2d` use SSD persistent
    disks.
