How to Use AWS Glue to Move and Transform Data

• Serverless ETL service for data integration
  
• Automatically discovers and catalogs data
  
• Transforms and moves data to S3, Redshift, or Athena

Open AWS Glue

1. Log in to the AWS Management Console.
   
2. In the search bar, type “Glue” and open AWS Glue.

Create a Database

The database will store metadata about your tables.

1. In the Glue console, go to Data Catalog , then Databases.
   
2. Click Add database.
   
3. Enter a name, for example mygluedb.
   
4. Click Create.
   

Create a Crawler

A crawler scans your data source (like S3) and automatically builds a table in the Glue Data Catalog.

1. Go to Data Catalog ,then Crawlers.
   
2. Click Create crawler.
   
3. Give it a name, e.g., s3_data_crawler.
   
4. Source type: Choose Data stores.
   
5. Connection type: Select S3 and browse to your bucket (s3://sourcedata/).
   
6. IAM Role: Choose Create new IAM role .Glue will make one automatically.
   
7. Output: Choose your database (mygluedb).
   
8. Review all settings and click Create crawler.
   
9. Once created, click Run crawler.
   

When it finishes, you’ll see a new table under your Glue database.

Create an ETL Job

Now we’ll transform and move the data.

1. Go to ETL Jobs then Jobs  then  Create job.
   
2. Choose Visual with a source and target.
   
3. Select your source table (from the crawler).
   
4. Choose Amazon S3 as the target.
   
   • Set a target path like s3://destdata/.
     
5. Click Next to view the script . Glue automatically generates a PySpark script.
   
6. Click Save and run job.
   

AWS Glue will now extract, transform, and load your data to the target bucket.

Check the Output

• Go to your target S3 bucket (s3://destdata/)
  
• You should see new files with transformed data.
