How do I import a DynamoDB table exported to S3 as a new table?

Question

I don't want to use data pipeline because it is too cumbersome. I also have a relatively small table so it would be heavy handed to use data pipeline for it- I could run a script locally to do the import because it's so small.

I used the fully managed Export to S3 feature to export a table to a bucket (in a different account): https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DataExport.html

What are my options now for importing that to a new table in the other account?

If there isn't a managed feature for this, does AWS provide a canned script I can point at an S3 folder and give the name of the new table I want to create from it?

Answer 1

As of 18 August 2022, this feature is now built into DynamoDB and you need no other services or code.

Answer 2

You may want to create a AWS Data Pipeline which already has recommended template for importing DynamoDB data from S3:

This is the closes you can get to a "managed feature" where you select the S3 prefix and the DynamoDB table.

Answer 3

Another AWS-blessed option is a cross-account DynamoDB table replication that uses Glue in the target account to import the S3 extract and Dynamo Streams for ongoing replication.

Answer 4

Amazon DyanamoDB now supports importing data from S3 buckets to new DynamoDB tables from this blog post .

The steps for importing data from S3 buckets can be found in their developer guide .
