DynamoDB - Backup and Recovery

You want to export a DynamoDB table Sales to S3 but only for data as it was exactly at 2024-05-01T12:00:00Z. Which approach correctly achieves this?

ACreate a new table snapshot manually and export it

BExport the whole table and then filter data in S3

CUse <code>scan</code> API with a filter for that timestamp and export results manually

DUse <code>export-table-to-point-in-time</code> with <code>--export-time 2024-05-01T12:00:00Z</code> option

Step-by-Step Solution

Solution:

Step 1: Understand point-in-time export
The export-table-to-point-in-time command supports --export-time to export data as it was at a specific timestamp.
Step 2: Compare other options
Export the whole table and then filter data in S3 exports all data, not filtered by time. Use scan API with a filter for that timestamp and export results manually requires manual filtering and export. Create a new table snapshot manually and export it is not a valid DynamoDB feature.
Final Answer:
Use export-table-to-point-in-time with --export-time 2024-05-01T12:00:00Z option -> Option D
Quick Check:
Export with --export-time = point-in-time snapshot [OK]

Quick Trick: Use --export-time to get data at specific timestamp [OK]

Common Mistakes:

MISTAKES

Exporting full table then filtering externally
Trying to filter with scan API before export
Assuming manual snapshot creation is needed
