Use AWS Lambda to trigger the ETL process directly from RDS, bypassing Glue and loading data directly into Redshift.

Set up Amazon EventBridge to monitor RDS for new transactions, trigger AWS Glue jobs for transformation, and use AWS Step Functions to orchestrate the workflow, ensuring data is loaded into Redshift efficiently.

Manually run AWS Glue jobs periodically to extract data from RDS, transform it, and then use a script to load the transformed data into Redshift.

Use Amazon S3 as an intermediary storage, dump data from RDS to S3, trigger Glue jobs from S3 events, and then load data from S3 to Redshift.
