Copy tables between two environments - Redshift

Question

I have a requirement to copy data between tables of two different instances in redshift.

The first one is dev environment and the second one is stage environment.

The requirement is to copy a table from dev to stage.

Instance 1: Dev
URL      :  link1
username : userdev
password: passdev
schema  : schema1
tablename: table1

Instance 2: Stage
URL:        link2
username:  userstage
password:  passstage
schema:   schema2
tablename: table2

Is there a way to copy between these instances?

I do not want to use the copy utility. I need a script.

Answer 1

Please have a look at out Unload/Copy Utility: https://github.com/awslabs/amazon-redshift-utils/tree/master/src/UnloadCopyUtility

The utility automates the process you've described above.

Answer 2

If it one time you can use copy command .

First copy data from instance-1 to S3. Then from S3 to instance-2.

If you need to do this daily use AWS Lambda with A JDBC connection to redshift with S3 as mediator.
