Request Syntax

client.export_table_to_point_in_time(
    TableArn='string',
    ExportTime=datetime(2015, 1, 1),
    ClientToken='string',
    S3Bucket='string',
    S3BucketOwner='string',
    S3Prefix='string',
    S3SseAlgorithm='AES256'|'KMS',
    S3SseKmsKeyId='string',
    ExportFormat='DYNAMODB_JSON'|'ION'
)
type TableArn:

string

param TableArn:

[REQUIRED]

The Amazon Resource Name (ARN) associated with the table to export.

type ExportTime:

datetime

param ExportTime:

Time in the past from which to export table data. The table export will be a snapshot of the table's state at this point in time.

type ClientToken:

string

param ClientToken:

Providing a ClientToken makes the call to ExportTableToPointInTimeInput idempotent, meaning that multiple identical calls have the same effect as one single call.

A client token is valid for 8 hours after the first request that uses it is completed. After 8 hours, any request with the same client token is treated as a new request. Do not resubmit the same request with the same client token for more than 8 hours, or the result might not be idempotent.

If you submit a request with the same client token but a change in other parameters within the 8-hour idempotency window, DynamoDB returns an IdempotentParameterMismatch exception.

This field is autopopulated if not provided.

type S3Bucket:

string

param S3Bucket:

[REQUIRED]

The name of the Amazon S3 bucket to export the snapshot to.

type S3BucketOwner:

string

param S3BucketOwner:

type S3Prefix:

string

param S3Prefix:

The Amazon S3 bucket prefix to use as the file name and path of the exported snapshot.

type S3SseAlgorithm:

string

param S3SseAlgorithm:

Type of encryption used on the bucket where export data will be stored. Valid values for S3SseAlgorithm are:

  • AES256 - server-side encryption with Amazon S3 managed keys

  • KMS - server-side encryption with AWS KMS managed keys

type S3SseKmsKeyId:

string

param S3SseKmsKeyId:

The ID of the AWS KMS managed key used to encrypt the S3 bucket where export data will be stored (if applicable).

type ExportFormat:

string

param ExportFormat:

The format for the exported data. Valid values for ExportFormat are DYNAMODB_JSON or ION.
