Using AWS Glue to transform data from DynamoDB to Redshift.

Hello everyone,

I'm new with AWS Glue. I'm doing a lab to move data from DynamoDB to Redshift with AWS Glue and my job does not succeed.
I test several times but none of them works (assume that IAM roles are correct).

With Dynamodb:

• Do I need to create a connection to dynamodb using JDBC ? (It's weird because at connection access there is no username or password to fill in).
• I need to create the data target first or just create it while add job?

With Redshift:

• After creating cluster, should I add table into public schema or just leave it as default?
• Do I need a S3 Endpoint to complete the lab? ( because It requires a S3 endpoint to test connection successfully)

Any suggestions about this case is a big help for me.
Thanks,
natuan
