AWS cluster properties

AWS cluster properties

When you set up a Databricks Delta connection, configure the connection properties based on the cluster environment you select.
The following table describes the Databricks Delta connection properties that apply when you select the AWS cluster environment:
Property
Description
S3 Access Key
The key to access the Amazon S3 bucket.
S3 Secret Key
The secret key to access the Amazon S3 bucket.
S3 Data Bucket
The existing bucket to store the Databricks Delta data.
S3 Staging Bucket
1
The existing bucket to store staging files.
S3 Authentication Mode
The authentication mode to access Amazon S3. You can select one of the following authentication types:
  • Permanent IAM credentials. Uses the S3 access key and S3 secret key to connect to Databricks Delta.
  • IAM Assume Role
    1
    . Uses the AssumeRole for IAM authentication to connect to Databricks Delta.
IAM Role ARN
1
The Amazon Resource Number (ARN) of the IAM role assumed by the user to use the dynamically generated temporary security credentials.
Set the value of this property if you want to use the temporary security credentials to access the Amazon S3 staging bucket.
For more information about how to get the ARN of the IAM role, see the AWS documentation.
Use EC2 Role to Assume Role
1
Optional. Select the check box to enable the EC2 role to assume another IAM role specified in the IAM Role ARN option.
The EC2 role must have a policy attached with a permission to assume an IAM role from the same or different AWS account.
S3 Region Name
1
The AWS cluster region in which the bucket you want to access resides.
Select a cluster region if you choose to provide a custom JDBC URL that does not contain a cluster region name in the JDBC URL connection property.
S3 Service Regional Endpoint
The S3 regional endpoint when the S3 data bucket and the S3 staging bucket need to be accessed through a region-specific S3 regional endpoint.
Default is
s3.amazonaws.com
.
Zone ID
1
The zone ID for the Databricks job cluster.
Applies only if you want to create a Databricks job cluster in a particular zone at runtime.
For example,
us-west-2a
.
The zone must be in the same region where your Databricks account resides.
EBS Volume Type
1
The type of EBS volumes launched with the cluster.
EBS Volume Count
1
The number of EBS volumes launched for each instance. You can choose up to 10 volumes.
In a Databricks Delta connection, specify at least one EBS volume for node types with no instance store. Otherwise, cluster creation fails.
EBS Volume Size
1
The size of a single EBS volume in GiB launched for an instance.
1
Doesn't apply to mappings in advanced mode.
