DataRepositoryAssociation - Amazon FSx

DataRepositoryAssociation

The configuration of a data repository association that links an Amazon FSx for Lustre file system to an Amazon S3 bucket. The data repository association configuration object is returned in the response of the following operations:

  • CreateDataRepositoryAssociation

  • UpdateDataRepositoryAssociation

  • DescribeDataRepositoryAssociations

Data repository associations are supported only for file systems with the Persistent_2 deployment type.

Contents

AssociationId

The system-generated, unique ID of the data repository association.

Type: String

Length Constraints: Minimum length of 13. Maximum length of 23.

Pattern: ^(dra-[0-9a-f]{8,})$

Required: No

BatchImportMetaDataOnCreate

A boolean flag indicating whether an import data repository task to import metadata should run after the data repository association is created. The task runs if this flag is set to true.

Type: Boolean

Required: No

CreationTime

The time that the resource was created, in seconds (since 1970-01-01T00:00:00Z), also known as Unix time.

Type: Timestamp

Required: No

DataRepositoryPath

The path to the Amazon S3 data repository that will be linked to the file system. The path can be an S3 bucket or prefix in the format s3://myBucket/myPrefix/. This path specifies where in the S3 data repository files will be imported from or exported to.

Type: String

Length Constraints: Minimum length of 3. Maximum length of 4357.

Pattern: ^[^\u0000\u0085\u2028\u2029\r\n]{3,4357}$

Required: No

FailureDetails

Provides detailed information about the data respository if its Lifecycle is set to MISCONFIGURED or FAILED.

Type: DataRepositoryFailureDetails object

Required: No

FileSystemId

The globally unique ID of the file system, assigned by Amazon FSx.

Type: String

Length Constraints: Minimum length of 11. Maximum length of 21.

Pattern: ^(fs-[0-9a-f]{8,})$

Required: No

FileSystemPath

A path on the file system that points to a high-level directory (such as /ns1/) or subdirectory (such as /ns1/subdir/) that will be mapped 1-1 with DataRepositoryPath. The leading forward slash in the name is required. Two data repository associations cannot have overlapping file system paths. For example, if a data repository is associated with file system path /ns1/, then you cannot link another data repository with file system path /ns1/ns2.

This path specifies where in your file system files will be exported from or imported to. This file system directory can be linked to only one Amazon S3 bucket, and no other S3 bucket can be linked to the directory.

Note

If you specify only a forward slash (/) as the file system path, you can link only 1 data repository to the file system. You can only specify "/" as the file system path for the first data repository associated with a file system.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 4096.

Pattern: ^[^\u0000\u0085\u2028\u2029\r\n]{1,4096}$

Required: No

ImportedFileChunkSize

For files imported from a data repository, this value determines the stripe count and maximum amount of data per file (in MiB) stored on a single physical disk. The maximum number of disks that a single file can be striped across is limited by the total number of disks that make up the file system.

The default chunk size is 1,024 MiB (1 GiB) and can go as high as 512,000 MiB (500 GiB). Amazon S3 objects have a maximum size of 5 TB.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 512000.

Required: No

Lifecycle

Describes the state of a data repository association. The lifecycle can have the following values:

  • CREATING - The data repository association between the FSx file system and the S3 data repository is being created. The data repository is unavailable.

  • AVAILABLE - The data repository association is available for use.

  • MISCONFIGURED - Amazon FSx cannot automatically import updates from the S3 bucket or automatically export updates to the S3 bucket until the data repository association configuration is corrected.

  • UPDATING - The data repository association is undergoing a customer initiated update that might affect its availability.

  • DELETING - The data repository association is undergoing a customer initiated deletion.

  • FAILED - The data repository association is in a terminal state that cannot be recovered.

Type: String

Valid Values: CREATING | AVAILABLE | MISCONFIGURED | UPDATING | DELETING | FAILED

Required: No

ResourceARN

The Amazon Resource Name (ARN) for a given resource. ARNs uniquely identify AWS resources. We require an ARN when you need to specify a resource unambiguously across all of AWS. For more information, see Amazon Resource Names (ARNs) in the AWS General Reference.

Type: String

Length Constraints: Minimum length of 8. Maximum length of 512.

Pattern: ^arn:(?=[^:]+:fsx:[^:]+:\d{12}:)((|(?=[a-z0-9-.]{1,63})(?!\d{1,3}(\.\d{1,3}){3})(?![^:]*-{2})(?![^:]*-\.)(?![^:]*\.-)[a-z0-9].*(?<!-)):){4}(?!/).{0,1024}$

Required: No

S3

The configuration for an Amazon S3 data repository linked to an Amazon FSx Lustre file system with a data repository association. The configuration defines which file events (new, changed, or deleted files or directories) are automatically imported from the linked data repository to the file system or automatically exported from the file system to the data repository.

Type: S3DataRepositoryConfiguration object

Required: No

Tags

A list of Tag values, with a maximum of 50 elements.

Type: Array of Tag objects

Array Members: Minimum number of 1 item. Maximum number of 50 items.

Required: No
