Copy AWS DynamoDB content between tables
Small NodeJS solution to copy content between two DynamoDB tables.
AWS DynamoDB does not support renaming tables or easy copying of content between two DynamoDB tables.
So this is a small dumb script that scans the whole table (mind the consumed capacity) and uses batchWrite to insert into the target table.
AWS Batch Write has two restrictions - max 25 items and 400kb per write. The later is not supported :S
Requirements
Node >=13 due to import syntax
Install
npm i
or yarn
Usage:
TABLEFROM
: Name of the source table to scan
TABLETO
: Name of the target table
REGION
: AWS Region for both tables (cross-region is possible, but noy yet)
AWSPROFILE
: Name of the AWS profile on the user account. AWS Key (env?) is not supported yet
node index.js --from TABLEFROM --to TABLETO --region REGION --profile AWSPROFILE
or
npm start -- --from TABLEFROM --to TABLETO --region REGION --profile AWSPROFILE
Example:
npm start -- --from oldTable --to newTable --region us-east-1 --profile default
