Discover

• • An Easy Catalog: AWS Glue logs all metadata kept in data stores on an AWS account regardless of location. The catalog comprises all categories and formats, including table definitions, schemas, and other control information. It can compute statistics, manage partitions, and run queries efficiently. It also catalogs how data changes over time with snapshots.

• • Data Discovery: AWS Glue has a feature called crawlers that develop interconnectivity between a source and a target data store.  Afterward, it sifts through a prioritized list of classifiers to determine the schema for the data and generates subsequent metadata for the catalog.  Crawlers can be set up to run on certain time triggers, including on a schedule, on-demand, or after-event triggers.

• • Schema Controls: The AWS Glue Schema Registry is a set of manual controls for validating the data stream using Apache Avro schemas. It uses Apache-licensed serializers and deserializers to integrate Java applications intended for Apache Kafka, Apache Flink, and AWS Lambda (link). This helps AWS Glue significantly improve data quality and avoid data loss due to sudden changes.

• • Rapid Scaling: Like many other services on AWS, AWS Glue also supports autoscaling, which allows for either sharply increasing or decreasing resources depending on the workload’s demand. Resources are only procured as needed, and AWS Glue will never overprovision more resources than necessary, helping to avoid needing to pay for unused assets.

Preparation

• • Duplicate Reduction: It’s not uncommon to have duplicated data bits across data sources.  AWS Glue helps to clean out these superfluous instances through pre-trained machine learning using another service feature called FindMatches.  Even if the two records are slightly different, FindMatches can still recognize both as matching or not. It will delete the match, retaining at least one version across the databases within its control.

• • ETL Code: AWS Glue ETL (extract, transform, and load) has development endpoints for editing, debugging code, and stress-testing with options for what IDE or notebook it’s done on.  On the side, there are a bunch of customizable templates for readers and writers that can be imported to an AWS Glue job or shared with other developers via GitHub.

• • Normalizing Code: AWS Glue’s DataBrew has an interactive and basic UI for data analysts and scientists who may not be familiar with programming.  It’s point-and-click, so moving data between database types and AWS services is very simple.
