View as Markdown

ClusterRevision object

Represents a cluster revision.

Only the 100 most recent revisions are stored for each cluster.

revision_idstring

ID of the cluster revision.

create_timestring

Time when the cluster revision was created.

settingsobject

Settings used to create/edit the cluster.

Show child attributesHide child attributes
apply_policy_default_valuesboolean

When set to true, fixed and default values from the policy will be used for fields that are omitted. When set to false, only fixed values from the policy will be applied.

Default: false

cluster_namestring

Cluster name requested by the user. This doesn't have to be unique. If not specified at creation, the cluster name will be an empty string. For job clusters, the cluster name is automatically set based on the job and job run IDs.

spark_versionstring

The Spark version of the cluster, e.g. 3.3.x-scala2.11. A list of available Spark versions can be retrieved by using the clusters/sparkVersions API call.

spark_confobject

An object containing a set of optional, user-specified Spark configuration key-value pairs. Users can also pass in a string of extra JVM options to the driver and the executors via spark.driver.extraJavaOptions and spark.executor.extraJavaOptions respectively.

aws_attributesobject

Attributes related to clusters running on Amazon Web Services. If not specified at cluster creation, a set of default values will be used.

Show child attributesHide child attributes
first_on_demandint32

The first first_on_demand nodes of the cluster will be placed on on-demand instances. If this value is greater than 0, the cluster driver node in particular will be placed on an on-demand instance. If this value is greater than or equal to the current cluster size, all nodes will be placed on on-demand instances. If this value is less than the current cluster size, first_on_demand nodes will be placed on on-demand instances and the remainder will be placed on availability instances. Note that this value does not affect cluster size and cannot currently be mutated over the lifetime of a cluster.

Default: 0

availabilitystring

Default: SPOT_WITH_FALLBACK

Values: SPOT, ON_DEMAND, SPOT_WITH_FALLBACK

zone_idstring

Identifier for the availability zone/datacenter in which the cluster resides. This string will be of a form like "us-west-2a". The provided availability zone must be in the same region as the <Databricks> deployment. For example, "us-west-2a" is not a valid zone id if the <Databricks> deployment resides in the "us-east-1" region. This is an optional field at cluster creation, and if not specified, the zone "auto" will be used. If the zone specified is "auto", will try to place cluster in a zone with high availability, and will retry placement in a different AZ if there is not enough capacity.

The list of available zones as well as the default value can be found by using the List Zones method.

instance_profile_arnstring

Nodes for this cluster will only be placed on AWS instances with this instance profile. If ommitted, nodes will be placed on instances without an IAM instance profile. The instance profile must have previously been added to the <Databricks> environment by an account administrator.

This feature may only be available to certain customer plans.

spot_bid_price_percentint32

The bid price for AWS spot instances, as a percentage of the corresponding instance type's on-demand price. For example, if this field is set to 50, and the cluster needs a new r3.xlarge spot instance, then the bid price is half of the price of on-demand r3.xlarge instances. Similarly, if this field is set to 200, the bid price is twice the price of on-demand r3.xlarge instances. If not specified, the default value is 100. When spot instances are requested for this cluster, only spot instances whose bid price percentage matches this field will be considered. Note that, for safety, we enforce this field to be no more than 10000.

Default: 100

ebs_volume_typestring

The type of EBS volumes that will be launched with this cluster.

Values: GENERAL_PURPOSE_SSD, THROUGHPUT_OPTIMIZED_HDD

ebs_volume_countint32

The number of volumes launched for each instance. Users can choose up to 10 volumes. This feature is only enabled for supported node types. Legacy node types cannot specify custom EBS volumes. For node types with no instance store, at least one EBS volume needs to be specified; otherwise, cluster creation will fail.

These EBS volumes will be mounted at /ebs0, /ebs1, and etc. Instance store volumes will be mounted at /local_disk0, /local_disk1, and etc.

If EBS volumes are attached, <Databricks> will configure Spark to use only the EBS volumes for scratch storage because heterogenously sized scratch devices can lead to inefficient disk utilization. If no EBS volumes are attached, <Databricks> will configure Spark to use instance store volumes.

Please note that if EBS volumes are specified, then the Spark configuration spark.local.dir will be overridden.

Default: 0

ebs_volume_sizeint32

The size of each EBS volume (in GiB) launched for each instance. For general purpose SSD, this value must be within the range 100 - 4096. For throughput optimized HDD, this value must be within the range 500 - 4096.

ebs_volume_iopsint32

If using gp3 volumes, what IOPS to use for the disk. If this is not set, the maximum performance of a gp2 volume with the same volume size will be used.

ebs_volume_throughputint32

If using gp3 volumes, what throughput to use for the disk. If this is not set, the maximum performance of a gp2 volume with the same volume size will be used.

If this value is greater than or equal to the current cluster size, all nodes will be placed on on-demand instances. If this value is less than the current cluster size, first_on_demand nodes will be placed on on-demand instances and the remainder will be placed on availability instances. Note that this value does not affect cluster size and cannot currently be mutated over the lifetime of a cluster.

Default: 1

availabilitystring

Availability type used for all subsequent nodes past the first_on_demand ones. Note: If first_on_demand is zero, this availability type will be used for the entire cluster.

Default: ON_DEMAND_AZURE

Values: SPOT_AZURE, ON_DEMAND_AZURE, SPOT_WITH_FALLBACK_AZURE

spot_bid_max_pricedouble

The max bid price to be used for Azure spot instances. The Max price for the bid cannot be higher than the on-demand price of the instance. If not specified, the default value is -1, which specifies that the instance cannot be evicted on the basis of price, and only on the basis of availability. Further, the value should > 0 or -1.

Default: -1

capacity_reservation_groupstringGA

The Azure capacity reservation group resource ID to use for launching VMs. When specified, VMs will be launched using the provided capacity reservation.

first_on_demandint32

The first first_on_demand nodes of the cluster will be placed on on-demand instances. This value should be greater than 0, to make sure the cluster driver node is placed on an on-demand instance. If this value is greater than or equal to the current cluster size, all nodes will be placed on on-demand instances. If this value is less than the current cluster size, first_on_demand nodes will be placed on on-demand instances and the remainder will be placed on availability instances. Note that this value does not affect cluster size and cannot currently be mutated over the lifetime of a cluster.

Default: 1

node_type_idstring

This field encodes, through a single value, the resources available to each of the Spark nodes in this cluster. For example, the Spark nodes can be provisioned and optimized for memory or compute intensive workloads. A list of available node types can be retrieved by using the clusters/listNodeTypes API call.

driver_node_type_idstring

The node type of the Spark driver. Note that this field is optional; if unset, the driver node type will be set as the same value as node_type_id defined above.

This field, along with node_type_id, should not be set if virtual_cluster_size is set. If both driver_node_type_id, node_type_id, and virtual_cluster_size are specified, driver_node_type_id and node_type_id take precedence.
