r/aws_dynamodb_table_export - support DynamoDB ExportTableToPointInTime API.

[mtt88]

Description

Add aws_dynamodb_table_export resource.

This change introduces support for the DynamoDB ExportTableToPointInTime API.

As issue #28917 describes, that this is not a conventional CRUD resources/API but will prove useful for ops tasks. Here are some observations and notes relating to this implementation:

• AWS provides no mechanism for deleting export table tasks. Even after deleting the table and S3 bucket used in an export, it's still visible in the AWS API - see the AWS Docs

You can find information about export tasks you've run in the past by using the list-exports command. This command returns a list of all exports you've created in the past 90 days. Note that although export task metadata expires after 90 days and jobs older than that are no longer returned by the list-exports command, the objects in your S3 bucket remain as long as their bucket policies allow. DynamoDB never deletes any of the objects it creates in your S3 bucket during an export.
even once we delete a DynamoDB table or the S3 bucket that we export to, the export will still be returned by this API.

• I was having difficulty writing a specific test for the export_time attribute as this needs to be greater than or equal to the time Point-in-time recovery was enabled. This value is returned from the https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_PointInTimeRecoveryDescription.html API but it's not currently accessible from any Terraform datasource/resource. It might be useful to add this?

• The provider has been configured to wait for either a COMPLETED or a FAILED status when creating the resource. This means that we will wait for the task to finish - AWS suggests that this will usually be less than 30minutes. I have only tested on empty or small DynamoDB tables. It would be good to understand how long these tasks may take on a large table - the default create timeout may need to be reviewed accordingly.

• I have not tested 'cross account' export (using the s3_bucket_owner attribute). Any help testing this would be useful.
