Programmatically load and upload data from Amazon Redshift to an Amazon S3-based Data Lake using Apache Airflow
In the following video demonstration, we will learn how to programmatically load and upload data from Amazon Redshift to an Amazon S3-based Data Lake using Apache Airflow. Since we are on AWS, we will be using the fully-managed Amazon Managed Workflows for Apache Airflow (Amazon MWAA). Using Airflow, we will
COPY raw data into staging tables, then merge that staging data into a series of tables. We will then load incremental data into Redshift on a regular schedule. Next, we will join and aggregate data from several tables and
UNLOAD the resulting dataset to an Amazon S3-based data lake. Lastly, we will catalog the data in S3 using AWS Glue and query with Amazon Athena.
