AWS Glue Made Easy
AWS Glue is a fully managed service for ETL. This service makes it easy and cost-effective to categorize, clean, improve and move your data efficiently and simply between different data stores.
It includes components such as a central metadata repository known as the AWS Glue Data Catalog, an ETL engine that automatically creates Python or Scala code, and a flexible task scheduling that handles dependency resolution, job monitoring, and retrieval.
AWS Glue is free and open source, which means that there is no infrastructure to set it up or handle.
Where else am I meant to use AWS Glue?
To create a data center to manage, disinfect, test, and format records.
You can migrate AWS Cloud data to your data center as well as shift it. You will also load data from a number of sources into your data repository for routine monitoring and analysis. Through keeping it in a data base, you combine knowledge from various aspects of your company to have a shared source of evidence for decision-making.
If you run a serverless test against the Amazon S3 data pool.
AWS Glue will archive your Amazon Simple Storage Service (Amazon S3) files, rendering it accessible for Amazon Athena and Amazon Redshift Spectrum queries. With the crawler, the metadata remains in line with the underlying details. With the aid of the AWS Glue Software Library, Athena and Redshift Spectrum will explicitly access the Amazon S3 software pool.
Using AWS Glue, you can view and evaluate data through a single centralized gui without loading it into different data silos.
If you decide to build an event-driven ETL pipeline
You will operate your ETL jobs as soon as new data is made accessible in Amazon S3 by calling your AWS Glue ETL jobs from the AWS Lambda function. You should also add this latest dataset in the AWS Glue Data Catalog, seeing it as part of the ETL job.
To understand the value of your results.
You can store your data using various AWS services and still maintain a unified view of your data using the AWS Glue Data Catalog. Use the Data Catalog to easily scan and explore the databases that you possess and retain the related information in one central repository.
The Data Collection also acts as a drop-in substitute for your external Apache Hive Metastor.
Adavtages of AWS Glue:
1. Less hassle
AWS Glue is distributed across a broad variety of AWS facilities. AWS Glue natively supports data housed in Amazon Aurora and all other Aws RDS systems, Amazon Redshift, and Amazon S3, combined with mutual storage engines and applications in the Virtual Private Cloud (Oracle VPC) operating Amazon EC2.
2. Cost-effective
AWS Glue works without a file. There is no network to support or maintain. AWS Glue manages the provisioning, setup and scaling of the services required to execute the ETL jobs in a completely controlled, flexible Apache Spark framework. You bill just for the services you use when the research is working.
3. More power
AWS Glue automates a large amount of work to create, manage and operate ETL jobs. This crawls the data sources, defines data types, and recommends schemas and transformations. AWS Glue dynamically creates a file to perform the system transformations and load operations.
