This is where AWS Glue comes in. AWS Glue is a fully managed extract, transform, and load (ETL) service that simplifies the process of moving data between data stores. In this comprehensive guide, we will take a deep dive into AWS Glue and explore its key features, benefits, and use cases. We will also compare it with traditional ETL tools to illustrate its advantages. If you&#8217;re curious about AWS Glue and want to learn about its functionalities and capabilities, read on.<\/p>\n<h2>What is ETL?<\/h2>\n<p><img decoding=\"async\" class=\"aligncenter size-large image-in-content\" src=\"https:\/\/gluesavior.com\/wp-content\/uploads\/2023\/05\/what-is-etl-glue993.webp\" alt=\"What Is Etl?\" \/><br \/>\nETL or Extract, Transform, Load is a process used in data integration to extract data from various sources, transform the data into a structure that&#8217;s suitable for analysis, and load the transformed data into a target destination. This process is crucial in modern data management and analysis, where data is spread across multiple sources and requires complex transformations to be usable. In the following sections, we&#8217;ll dive deeper into each step of ETL and explore how Amazon Web Services&#8217; AWS Glue simplifies this process. So, let&#8217;s get started without any delay!<\/p>\n<h3>Extract<\/h3>\n<p>During the ETL process, the first step is &#8220;Extract&#8221;, which is the process of extracting data from various sources such as databases, flat files, and other data sources. The data sources can be on-premises or in the cloud. The data is extracted in the form of structured, semi-structured, or unstructured data. The extracted data can be in different formats, such as CSV, JSON, Parquet, Avro, and more. <\/p>\n<p><strong>Extract Process Steps:<\/strong><\/p>\n<table>\n<tr>\n<th>Step<\/th>\n<th>Description<\/th>\n<\/tr>\n<tr>\n<td>Determine the data source<\/td>\n<td>In this step, you need to determine the data sources that you want to extract data from. These sources can be flat files, databases, or other sources.<\/td>\n<\/tr>\n<tr>\n<td>Connect to the data source<\/td>\n<td>You need to establish a connection to the data source to fetch the data. You can establish a connection using different protocols and APIs.<\/td>\n<\/tr>\n<tr>\n<td>Extract data<\/td>\n<td>After connecting to the data source, you can extract the data based on some predefined criteria such as SQL query or NoSQL query, data filters, or other criteria.<\/td>\n<\/tr>\n<tr>\n<td>Store data<\/td>\n<td>Once you have extracted the data, the data needs to be stored in a staging area so that it can be processed in the next step.<\/td>\n<\/tr>\n<\/table>\n<p>AWS Glue provides four ways to extract data from different sources: Glue ETL jobs, Glue crawlers, AWS Database Migration Service, and AWS Snowball. Glue ETL jobs provide the flexibility to extract data from different sources and transform the data according to the business requirement.<\/p>\n<p>Glue crawlers help extract metadata from the source data to create a data catalog that can be used for mapping data to the target destination. AWS Database Migration Service is used for extracting data from on-premises data sources and migrating that data to the AWS cloud. AWS Snowball is a petabyte-scale data transport solution that helps to get data into and out of AWS.<\/p>\n<p><strong>Now let&#8217;s move on to the next step of the ETL process which is &#8220;Transform&#8221;.<\/strong> For more information on AWS Glue, please refer to<a href=\"\/what-glue-to-use-for-gold-leaf\/\"> this article.<\/a><\/p>\n<h3>Transform<\/h3>\n<p>During the ETL process, the next step after extraction is transformation. This step involves manipulating the extracted data to make it suitable for the target data store or data warehouse. It mainly includes data cleaning, data mapping, data conversion, filtering, and aggregation. Transformation is a crucial step since it cleans up any inconsistencies in the data, resolves redundant data, and updates the data to the required schema. There are various <strong>transformation types<\/strong> that can be applied to the data, including:<\/p>\n<ul>\n<li><strong>Filtering:<\/strong> This involves removing or keeping specific data based on a particular criteria from the extracted data set.<\/li>\n<li><strong>Mapping:<\/strong> This involves converting the data values to a different format for usage in the target data store.<\/li>\n<li><strong>Normalization:<\/strong> This involves restructuring the data to eliminate redundancy, ensure data consistency, and improve data integrity.<\/li>\n<li><strong>Aggregating:<\/strong> This involves combining the data to form a summary of a particular category or group.<\/li>\n<li><strong>Joining:<\/strong> This involves combining data from two or more sources based on a particular identifier to form a single data set.<\/li>\n<li><strong>Validation:<\/strong> This involves verifying the data to ensure it conforms to a specific set of rules or guidelines.<\/li>\n<\/ul>\n<p>Transformations can be performed using different tools and programming languages, such as Python, SQL, and Java. AWS Glue provides built-in transformations such as <strong>join, pivot, and relationalize<\/strong> to help transform your data efficiently.<\/p>\n<p>For example, suppose you have data in different formats and need to extract it and bring it together in a unified format. You can use AWS Glue to transform the data to create a standardized schema for the data to be combined in the target data store or data warehouse. With AWS Glue, you can perform these transformations without having to worry about the underlying infrastructure or data management tasks. <\/p>\n<p>If you need to enhance your glue projects more with proper knowledge about glues and their features you can check out <a href=\"\/how-to-make-pva-glue\/\">how to make PVA glue<\/a> article.<\/p>\n<h3>Load<\/h3>\n<p>When it comes to loading in ETL, the transformed or modified data is finally put into a new location like a data warehouse or a data lake. This is the last step of ETL which completes the cycle and makes the data ready to use. In the loading phase of AWS Glue, you can choose your target data storage from a variety of options like Amazon S3, Amazon RDS, Amazon Redshift, and more. AWS Glue uses JDBC and ODBC drivers to connect to the data storage and apply the transformations. <\/p>\n<p><strong>Amazon S3<\/strong> is the most commonly used data storage in AWS Glue, due to its cheap storage and ease-of-use. S3 is an object-based storage service and Glue can easily read data from and write data to S3. AWS Glue also provides a feature called partition projection which helps in improving the query performance while querying large datasets stored in S3.<\/p>\n<p><strong>Amazon RDS<\/strong> is a managed relational database service provided by AWS which is also used as a target for AWS Glue loading. AWS Glue can load data into a variety of AWS RDS databases such as MySQL, PostgreSQL, Oracle, and SQL Server. Loading data through AWS Glue into Amazon RDS is a simple and easy-to-use process that requires minimal configuration.<\/p>\n<p><strong>Amazon Redshift<\/strong>  is another popular target data storage for AWS Glue loading. It is a fast, cost-effective, and scalable data warehouse solution provided by AWS. AWS Glue can easily load data into Redshift from various sources like S3, Amazon RDS, and more. AWS Glue automatically integrates with Amazon Redshift, which means you can quickly start loading data into Redshift without any additional setup.<\/p>\n<p>Whether you choose Amazon S3, Amazon RDS, Amazon Redshift, or any other storage solution, AWS Glue makes the loading process simple and streamlined. With just a few clicks, you can configure your target data storage and load data effortlessly.<\/p>\n<p>(internal link: \/how-long-should-elmer-wood-glue-dry\/)<\/p>\n<h2>What is AWS Glue?<\/h2>\n<p><img decoding=\"async\" class=\"aligncenter size-large image-in-content\" src=\"https:\/\/gluesavior.com\/wp-content\/uploads\/2023\/05\/what-is-aws-glue-glue993.webp\" alt=\"What Is Aws Glue?\" \/><br \/>\nAWS Glue is a fully-managed Extract, Transform, Load (ETL) service that makes it easy for you to move data between data stores.

It also provides hooks and extensions to customize and extend Glue&#8217;s functionality to meet your specific ETL requirements.<\/li>\n<li><strong>Integrations:<\/strong> AWS Glue seamlessly integrates with other AWS services like Amazon S3, Amazon Redshift, Amazon Athena, AWS Lambda, AWS Step Functions, and AWS CloudTrail. This allows you to build end-to-end data processing pipelines using a combination of these services.<\/li>\n<\/ul>\n<p>By leveraging these and other features, AWS Glue makes it easy and efficient to perform ETL tasks at any scale.<\/p>\n<h3>How does it work?<\/h3>\n<p>AWS Glue is a fully managed ETL (Extract, Transform, Load) service by Amazon Web Services that makes it easier to move data between data stores. It eliminates the need to write custom code for data cleaning, ETL processes, and data conversion. AWS Glue works by using crawlers to automatically detect schema changes in source data, then creating ETL jobs which can transform and load that data into the target data store.<\/p>\n<p><strong>The following table outlines the high-level process of how AWS Glue works:<\/strong><\/p>\n<table>\n<tr>\n<th>Step<\/th>\n<th>Description<\/th>\n<\/tr>\n<tr>\n<td>1.<\/td>\n<td>AWS Glue Crawler scans the data stored at the source to identify its format, schema, and partitioning. Based on these parameters, it generates table definitions in AWS Glue Data Catalog.<\/td>\n<\/tr>\n<tr>\n<td>2.<\/td>\n<td>AWS Glue ETL Job is created in the console to transform, filter, and aggregate source data. You can also choose to remove duplicates, drop null\/empty column values, and perform other transformations using Apache Spark ETL scripts. <\/td>\n<\/tr>\n<tr>\n<td>3.<\/td>\n<td>AWS Glue Job loads the transformed data into the target data store, such as Amazon Redshift, Amazon S3, or Amazon RDS. You can also choose to use JDBC or ODBC connection to load data into databases hosted outside of AWS. <\/td>\n<\/tr>\n<\/table>\n<p>AWS Glue eliminates the need for manual coding by automatically discovering data, generating metadata, and generating and executing ETL jobs. The service allows users to focus on business logic instead of maintaining data infrastructure. <\/p>\n<p>While there are a variety of traditional ETL tools available, AWS Glue&#8217;s serverless architecture makes it more cost-effective to use. It automatically scales to meet workload demands, so users only pay for the resources they actually use. Additionally, it integrates with other AWS services, such as Amazon S3 and AWS Lambda, to provide a more complete data pipeline solution. <\/p>\n<p><strong>Exploring the workflows of AWS Glue is just one step towards building a better understanding of how this service can help your business.<\/strong><\/p>\n<h3>AWS Glue Workflow<\/h3>\n<p><strong>AWS Glue Workflow:<\/strong><\/p>\n<p>The AWS Glue workflow enables you to create and specify a sequence of Glue activities into a complete data processing task. A workflow consists of multiple job and trigger defined in a Directed Acyclic Graph (DAG). It defines the relationships between several Glue components and their dependencies, enabling the streamlined processing of data. Here are the steps involved in the AWS Glue workflow:<\/p>\n<ul>\n<li><strong>Create a Crawler: <\/strong>In the first step, you create and configure a Crawler to access and sort your data source. AWS Glue will extract metadata from the specified data source and apply a schema to find the data&#8217;s structure.<\/li>\n<li><strong>Create a Glue Data Catalog:<\/strong> Once the metadata is gathered, AWS Glue will store it in the Data Catalog. The Data Catalog acts as a central repository and provides details of the structure and schema that was identified in this step.<\/li>\n<li><strong>Create Job:<\/strong> After accessing and defining the structure of the data, you can begin preparing, transforming and processing it with AWS Glue Job. It allows you to use various tools like PySpark, Python, or Scala to filter, process or aggregate data sets.<\/li>\n<li><strong>Trigger the Job:<\/strong> Once the Job is ready, you can trigger it to start executing. If you don&#8217;t want to trigger the job manually every time, AWS Glue provides pre-configured triggers like run on-demand, run on a schedule, or run when a new file is added to S3 buckets.<\/li>\n<li><strong>Operations Management:<\/strong> The workflow provides you with the option to monitor and manage your clusters, crawlers, and pipelines seamlessly. It has a centralized console that lets you track how various processes interact with each other and discover bottlenecks or failures from the logs.<\/li>\n<\/ul>\n<p>The workflow of AWS Glue offers a user-friendly approach to manage data processing tasks. It eliminates the need to monitor different processes, dependencies and ensures that they run efficiently and seamlessly. By defining and configuring the DAGs, you can design complex and sophisticated solutions for processing data at scale.<\/p>\n<p>The AWS Glue workflow is an effective way of handling ETL processing and automating those processing pipelines, providing a streamlined experience that removes much of the complexity and difficulty that has been associated with traditional ETL solutions.<\/p>\n<div class='code-block code-block-1' style='margin: 8px 0; clear: both;'>\n<h2>Discover Top 3 Glue Bestsellers<\/h2><p >No products found.<\/p><\/div>\n<h2>Why use AWS Glue?<\/h2>\n<p><img decoding=\"async\" class=\"aligncenter size-large image-in-content\" src=\"https:\/\/gluesavior.com\/wp-content\/uploads\/2023\/05\/why-use-aws-glue-glue993.webp\" alt=\"Why Use Aws Glue?\" \/><br \/>\nOne might wonder, &#8220;What advantages does AWS Glue offer over traditional ETL tools?&#8221; It&#8217;s important to understand the benefits of AWS Glue to determine if it is the right solution for your data integration needs.
