I use this CLI command for exporting and then later importing data from/to DynamoDB (small amounts of data – eg. upto a few hundred items).
It does take a while to get data back into DynamoDB, as it’s doing it line-by-line, rather than as a batch … but gets the job done!
Export;
aws dynamodb scan --table-name source-table-name --no-paginate > data.json
Import;
cat data.json | jq -c '.Items[]' | while read -r line; do aws dynamodb put-item --table-name destination-table-name --item "$line"; done
This can be done in one line as well;
aws dynamodb scan --table-name source-table-name --no-paginate | jq -c '.Items[]' | while read -r line; do aws dynamodb put-item --table-name destination-table-name --item "$line"; done
