To create an ML transform via the console, customers first select the transform type (such as Record Deduplication or Record Matching) and provide the appropriate data sources previously discovered in Data Catalog.
On the other hand, AWS Data Pipeline allows you to create data transformations through APIs and also through JSON, while only providing support for DynamoDB, SQL and Redshift. AWS Glue ETL jobs can either be triggered on a schedule or on a job completion event. Depending on the transform, customers may then be asked to provide ground truth label data for training or additional parameters. Triggers can watch one or more jobs as well as invoke one or more jobs. It provides a serverless Apache Flink runtime that automatically scales without servers and durably saves application state. AWS Glue is a serverless platform. For instance, the same movie might be variously identified as “Star Wars”, “Star Wars: A New Hope”, and “Star Wars: Episode IV—A New Hope (Special Edition)”.Automatically group all related products together in your storefront by identifying equivalent items in an apparel product catalog where you want to define “equivalent” to mean that they are the same ignoring differences in size and color. If you choose to use a development endpoint to interactively develop your ETL code, you will pay an hourly rate, billed per second, for the time your development endpoint is provisioned, with a 10-minute minimum. You can also run Hive DDL statements via the An AWS Glue crawler connects to a data store, progresses through a prioritized list of classifiers to extract the schema of your data and other statistics, and then populates the Glue Data Catalog with this metadata. AWS Glue infers, evolves, and monitors your ETL jobs to greatly simplify the process of creating and maintaining jobs.

As a serverless platform, AWS Glue has the edge over EMR in terms of operational flexibility.So if you want to use either one of these tools for ETL operations only, I would suggest you go for Amazon Glue from operational perspectives.In AWS Glue, you cannot store temp files, executable files on your end due to serverless infrastructure. As an example, consider the problem of matching a large database of customers to a small database of known fraudsters. Customers can then execute this Transform on their database to find matching records or they can ask FindMatches to give them additional records to label to push their ML Transform to higher levels of accuracy. It also gives you control over the compute resources that run your code and allows you to access the Amazon EMR clusters or EC2 instances. You can customize Glue crawlers to classify your own file types.You simply run an ETL job that reads from your Apache Hive Metastore, exports the data to an intermediate format in No. Let us know in the comments section.You can contribute any number of in-depth posts on all things data. It includes ETL capabilities that are designed to make data easier to process after delivery, but does not include the advanced ETL capabilities that AWS Glue supports.FindMatches generally solves Record Linkage and Data Deduplication problems. This allows you to focus on your ETL job and not worry about configuring and managing the underlying compute resources. A Glue ETL job requires a minimum of 2 DPUs. Using AWS Data Pipeline, you define a pipeline composed of the “data sources” that contain your data, the “activities” or business logic such as EMR jobs or SQL queries, and the “schedule” on which your business logic executes. You can either have a scheduled trigger that invokes jobs periodically, an on-demand trigger, or a job completion trigger.AWS Glue monitors job event metrics and errors, and pushes all notifications to Yes. It also allows you to setup, orchestrate, and monitor complex data flows.Yes, EMR does work out to be cheaper than Glue, and this is because Glue is meant to be serverless and fully managed by AWS, so the user doesn’t have to worry about the infrastructure running behind the scenes, but EMR requires a whole lot of configuration to set up.
