DynamoDB2MYSQL

Node.js script to transfer DynamoDB table to MySQL

All you need to do is create config.json file in that same directory as such:

{
	"aws":
	{
		"key": "AWS_ACCESS_KEY",
		"secret": "AWS_SECRET_KEY",
		"region": "AWS_REGION",
		"limit": DYNAMODB_LIMIT_ROWS_PER_READ
	},
	"mysql":
	{
		"host": "MYSQL_HOST",
		"port": "MYSQL_PORT",
		"user": "MYSQL_USER",
		"password": "MYSQL_PASSWORD",
		"database": "MYSQL_DATABASE_NAME"
	}
}

If you want to notify on transfer complete or execution fails, you should add section "notify" in config.json as such:

{
	"aws":
	{
		"key": "AWS_ACCESS_KEY",
		"secret": "AWS_SECRET_KEY",
		"region": "AWS_REGION",
		"limit": DYNAMODB_LIMIT_ROWS_PER_READ
	},
	"mysql":
	{
		"host": "MYSQL_HOST",
		"port": "MYSQL_PORT",
		"user": "MYSQL_USER",
		"password": "MYSQL_PASSWORD",
		"database": "MYSQL_DATABASE_NAME"
	},
	"notify":
	{
		"sender": "required@must.be.verified",
		"recipient": "required@must.be.verified",
	}
}

Notification using Amazon SES.

The output is executed sql.
