Glue Jobs & Multiple tables

0

A customer needs to ETL multiple tables from RDS into S3 and Redshift.

Let's say they need to combine data from 6 tables to load into S3.

I tried helping them setup the Glue Jobs for this process, but it's not clear what the best and efficient way is to load these tables into S3 or Redshift: When you create a Glue Job, you can only select 1 table as a data source.

Do they need to create a Glue Job for each table or customize the generated Glue jobs to include all tables?

Yes, they need to customize the generated Glue job to include multiple tables and join them. The Glue Job creation UI just creates a simple template job with one source and one target but in reality most jobs needs multiple sources and some need multiple targets as well.
