In this post, we discuss how to leverage the automatic code generation process in AWS Glue ETL to simplify common data manipulation tasks, such as data type conversion and flattening complex structures. We also explore using AWS Glue Workflows to build and orchestrate data pipelines of varying complexity. Lastly, we look at how you can leverage the power of SQL, with the use of AWS Glue ETL and Glue Data Catalog, to query and transform your data.

This post walks you through accessing the AWS COVID-19 data lake through the AWS Glue Data Catalog via Amazon SageMaker or Jupyter and using the open-source AWS Data Wrangler library. AWS Data Wrangler is an open-source Python package that extends the power of Pandas library to AWS and connects DataFrames and AWS data-related services (such as Amazon Redshift, Amazon S3, AWS Glue, Amazon Athena, and Amazon EMR). For more information about what you can build by using this data lake, see the associated public Jupyter notebook on GitHub.

Amazon Redshift Federated Query allows you to combine the data from one or more Amazon RDS for PostgreSQL and Amazon Aurora PostgreSQL databases with data already in Amazon Redshift. You can also combine such data with data in an Amazon S3 data lake.

You may have heard the saying that the best ETL is no ETL. Amazon Redshift now makes this possible with Federated Query. In its initial release, this feature lets you query data in Amazon Aurora PostgreSQL or Amazon RDS for PostgreSQL using Amazon Redshift external schemas. Federated Query also exposes the metadata from these source databases through system views and driver APIs, which allows business intelligence tools like Tableau and Amazon Quicksight to connect to Amazon Redshift and query data in PostgreSQL without having to make local copies.
