Research direction

Start by reproducing the s3print-to-dyno put command and inspect how dynamodb-replicator writes backups and how dyno deserializes them. Define whether the work is a restore option or compatible backup output; done means a documented or working path that restores a backup into a DynamoDB table without the shown parsing error.

Written by the indexing model from the issue text.

Description

It's nice that you have implemented such tool but there is not way to restore table from backup.

Questions:

  • why there is no restore option in dynamodb-replicator?
  • when I try to restore using dyno (which I assume can read these backups) I end up with error:

s3print s3://some-s3/ull/bba24099b07f53f5/0 | dyno put eu-west-1/TMP_ATSI_ARTIFICIAL_APPLICANT_ID
