How to Accelerate Building a Lake House Architecture with AWS Glue

Customers are building databases, data warehouses, and data lake solutions in isolation from each other, each having its own separate data ingestion, storage, management, and governance layers. Often these disjointed efforts to build separate data stores end up creating data silos, data integration complexities, excessive data movement, and data consistency issues. These issues are preventing customers from getting deeper insights. To overcome these issues and easily move data around, a Lake House approach on AWS was introduced.

In this blog post, we illustrate the AWS Glue integration components that you can use to accelerate building a Lake House architecture on AWS. We will also discuss how to derive persona-centric insights from your Lake House using AWS Glue.

Components of the AWS Glue integration system

AWS Glue is a serverless data integration service that facilitates the discovery, preparation, and combination of data. It can be used for analytics, machine learning, and application development. AWS Glue provides all of the capabilities needed for data integration. So you can start analyzing your data and putting it to use in minutes, rather than months.

The following diagram illustrates the various components of the AWS Glue integration system.

Connect – AWS Glue allows you to connect to various data sources anywhere

Glue connector: AWS Glue provides built-in support for the most commonly used data stores. You can use Amazon Redshift, Amazon RDS, Amazon Aurora, Microsoft SQL Server, MySQL, MongoDB, or PostgreSQL using JDBC connections. AWS Glue also allows you to use custom JDBC drivers in your extract, transform, and load (ETL) jobs. For data stores that are not natively supported such as SaaS applications, you can use connectors. You can also subscribe to several connectors offered in the AWS Marketplace.

Glue crawlers: You can use a crawler to populate the AWS Glue Data Catalog with tables. A crawler can crawl multiple data stores in a single pass. Upon completion, the crawler creates or updates one or more tables in your Data Catalog. Extract, transform, and load (ETL) jobs that you define in AWS Glue use these Data Catalog tables as sources and targets.

Catalog – AWS Glue simplifies data discovery and governance

Glue Data Catalog: The Data Catalog serves as the central metadata catalog for the entire data landscape.

Glue Schema Registry: The AWS Glue Schema Registry allows you to centrally discover, control, and evolve data stream schemas. With AWS Glue Schema Registry, you can manage and enforce schemas on your data streaming applications.

Data quality – AWS Glue helps you author and monitor data quality rules

Glue DataBrew: AWS Glue DataBrew allows data scientists and data analysts to clean and normalize data. You can use a visual interface, reducing the time it takes to prepare data by up to 80%. With Glue DataBrew, you can visualize, clean, and normalize data directly from your data lake, data warehouses, and databases.

Curate data: You can use either Glue development endpoint or AWS Glue Studio to curate your data.

AWS Glue development endpoint is an environment that you can use to develop and test your AWS Glue scripts. You can choose either Amazon SageMaker notebook or Apache Zeppelin notebook as an environment.

AWS Glue Studio is a new visual interface for AWS Glue that supports extract-transform-and-load (ETL) developers. You can author, run, and monitor AWS Glue ETL jobs. You can now use a visual interface to compose jobs that move and transform data, and run them on AWS Glue.

AWS Data Exchange makes it easy for AWS customers to securely exchange and use third-party data in AWS. This is for data providers who want to structure their data across multiple datasets or enrich their products with additional data. You can publish additional datasets to your products using the AWS Data Exchange.

Deequ is an open-source data quality library developed internally at Amazon, for data quality. It provides multiple features such as automatic constraint suggestions and verification, metrics computation, and data profiling.

Build a Lake House architecture faster, using AWS Glue

Figure 2 illustrates how you can build a Lake House using AWS Glue components.

The architecture flow follows these general steps:

  1. Glue crawlers scan the data from various data sources and populate the Data Catalog for your Lake House.
  2. The Data Catalog serves as the central metadata catalog for the entire data landscape.
  3. Once data is cataloged, fine-grained access control is applied to the tables through AWS Lake Formation.
  4. Curate your data with business and data quality rules by using Glue Studio, Glue development endpoints, or Glue DataBrew. Place transformed data in a curated Amazon S3 for purpose built analytics downstream.
  5. Facilitate data movement with AWS Glue to and from your data lake, databases, and data warehouse by using Glue connections. Use AWS Glue Elastic views to replicate the data across the Lake House.

Derive persona-centric insights from your Lake House using AWS Glue

Many organizations want to gather observations from increasingly larger volumes of acquired data. These insights help them make data-driven decisions with speed and agility. They must use a central data lake, a ring of purpose-built data services, and data warehouses based on persona or job function.

Figure 3 illustrates the Lake House inside-out data movement with AWS Glue DataBrew, Amazon Athena, Amazon Redshift, and Amazon QuickSight to perform persona-centric data analytics.

This shows how Lake House components serve various personas in an organization:

  1. Data ingestion: Data is ingested to Amazon Simple Storage Service (S3) from different sources.
  2. Data processing: Data curators and data scientists use DataBrew to validate, clean, and enrich the data. Amazon Athena is also used to run improvised queries to analyze the data in the lake. The transformation is shared with data engineers to set up batch processing.
  3. Batch data processing: Data engineers or developers set up batch jobs in AWS Glue and AWS Glue DataBrew. Jobs can be initiated by an event, or can be scheduled to run periodically.
  4. Data analytics: Data/Business analysts can now analyze prepared dataset in Amazon Redshift or in Amazon S3 using Athena.
  5. Data visualizations: Business analysts can create visuals in QuickSight. Data curators can enrich data from multiple sources. Admins can enforce security and data governance. Developers can embed QuickSight dashboard in applications.


Using a Lake House architecture will help you get persona-centric insights quickly from all of your data based on user role or job function. In this blog post, we describe several AWS Glue components and AWS purpose-built services that you can use to build Lake House architectures on AWS. We have also presented persona-centric Lake House analytics architecture using AWS Glue, to help you derive insights from your Lake House.
