StartTableMigration - Amazon S3

StartTableMigration

Starts migrating an AWS Glue Data Catalog table into a new table in a table bucket. The migration runs asynchronously: this operation returns the migration ID and its initial state, and you track progress with GetTableMigration.

The namespace must already exist, and a table with the specified name must not. The migration creates the table during planning and commits data to it as it runs. Until you call CompleteTableMigration, you can read the table but you can't write to it. If the migration fails or is cancelled, the table and the data already committed to it remain.

The migration first checks the source and the destination, and writes the table compatibility and object compatibility reports to the bucket that you specify in migrationOutput. If you set reviewMigrationPlan to true, the migration waits in the pendingReview state so that you can review the reports, and continues only when you call UpdateTableMigration with requestedState set to queued. If you don't continue or cancel the migration within 30 days, the migration fails. Otherwise it continues to migrate the data, and writes the object migration report when the migration ends. If planning fails, the migration writes no object migration report.

Permissions
  • You must have the s3tables:StartTableMigration permission to use this operation.

  • You must have the iam:PassRole permission on the role that you specify in roleARN, with a condition that allows passing it to migration.s3tables.amazonaws.com. The associated resource is the table bucket.

  • If destinationTable specifies SSE-KMS encryption, you must have the kms:DescribeKey and kms:GenerateDataKey permissions on the KMS key. You must also grant the S3 Tables maintenance principal access to the key. For more information, see Permissions requirements for S3 Tables SSE-KMS encryption.

Request Syntax

URI Request Parameters

The request does not use any URI parameters.

Request Body

The request accepts the following data in JSON format.

dataMigration

The maintenance settings and migration policies for the destination table.

Type: DataMigrationSettings object

Required: No

destinationTable

The table to create and migrate the source into.

Type: DestinationTable object

Required: Yes

migrationOutput

The bucket and prefixes that the migration writes its reports to. The bucket must be a general purpose bucket in your account and in the same Region as the table bucket, and the migration role must be able to write objects to it. Otherwise, the migration fails when it writes its first report.

Type: MigrationOutputConfiguration object

Required: Yes

reviewMigrationPlan

Specifies whether the migration waits in the pendingReview state, so that you can review the compatibility reports before it migrates any data. If true, the migration continues when you call UpdateTableMigration with requestedState set to queued. If you don't continue or cancel the migration within 30 days, the migration fails. The default is false.

Type: Boolean

Required: No

roleARN

The Amazon Resource Name (ARN) of the IAM role that the migration uses to read the source table and its data and to write the destination table and the reports. The role must be in your account, and its trust policy must allow migration.s3tables.amazonaws.com to assume it. You can limit the trust policy to the destination table bucket with the aws:SourceArn and aws:SourceAccount condition keys.

Type: String

Length Constraints: Minimum length of 20. Maximum length of 2048.

Pattern: arn:aws[-a-z0-9]*:iam::[0-9]{12}:role/.+

Required: Yes

source

The source table to migrate.

Type: SourceConfiguration object

Note: This object is a Union. Only one member of this object can be specified or returned.

Required: Yes

sourceType

The type of the source. It must match the member that you set in source.

Type: String

Valid Values: glueTable

Required: Yes

migrationId

The ID of the migration.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 64.

Pattern: [a-z0-9-]+
