DynamoDB: How To Move Out

Moving data from one place to another involves capturing changes, copying data, and replaying deltas to ensure both databases are in sync. Dual-writing can be used for migrations from DynamoDB, but it may not always be the most efficient option depending on factors like TTL. Back-filling historical data can be done using ETL, table scans, or exporting data to S3, each with its own pros and cons.
