ETL Processing Using AWS Data Pipeline and Amazon Elastic MapReduce
This blog post shows you how to build an ETL workflow that uses AWS Data Pipeline to schedule an Amazon Elastic MapReduce (Amazon EMR) cluster to clean and process web server logs stored in an Amazon Simple Storage Service (Amazon S3) bucket. AWS Data Pipeline is an ETL service that you can use to automate the movement and transformation of data.
Step 1: Determine Whether Log Files are Available in an Amazon S3 Bucket
The first step is to check whether files are available in the s3://emr-worksop/data/input/ {YYYY-MM-DD} location. This is passed as a variable myInputData. A variable can be referenced in other places by # {variable_name}.
Step 2: Creating an Amazon EMR Cluster with EMRFS
The data pipeline JSON code below launches a three-node Amazon EMR cluster with EMRFS with one master and two core nodes. terminateAfter terminates the cluster after one hour.
Step 3: Run emrfs sync to Update Metadata with the Contents of the Amazon S3 Bucket
For this, we use the preStepCommand feature. Amazon EMR’s documentation provides more information about this feature.
Step 4: Launch a Pig Job on the Amazon EMR Cluster
The Pig job is submitted to the Amazon EMR cluster as a Step. The input to this job are log files present in an Amazon S3 bucket referenced by variable myInputData. After processing the log file, the output is written to another Amazon S3 location referenced by the variable myTransformedData.
Step 5: Reuse the Amazon EMR Cluster to Launch a Hive job for Generating Reports
After the Pig job has cleaned the data, we kick off the Hive job to generate reports on same Amazon EMR cluster. Let’s take a closer look at this Hive script ( download the script to check it out).
Step 6: Clean EMRFS Metadata Older than Two Days (emrfs delete)
We do this post processing after both the jobs have completed on cluster. Amazon EMR documentation provides more information about EMRFS delete. For this we use the postStepCommand feature of AWS Data Pipeline which runs the command after successfully completing the step.

How to choose an ETL tool?
How do you pick the most suitable ETL tool for your business? Start by asking questions specific to your requirements: 1 Does an ETL tool integrate with every data source you use today? 2 Will it integrate with new data sources — even those that are less popular or custom-built? To be prepared to take advantage of new data sources, consider an extensible solution like Stitch, whose Singer open source framework lets you integrate new data sources. 3 What kind of reliability do you need? It’s tough to beat the fault tolerance of a cloud-native service. 4 What are your requirements for performance and scalability? 5 Does it meet your security requirements? Do you need to meet HIPAA, PCI, or GDPR compliance requirements? 6 Pricing models vary among ETL services. Does the solution charge by the hour, number of data sources, or a combination of factors? Make sure the solution is priced in a way that makes sense for your business’s usage. 7 What replication scheduling options are available and how is replication handled? What happens if a replication job is still running when the next is supposed to start? Can you specify a start time to establish a predictable schedule? 8 What types of support are available? Is quality documentation available online? Is in-app support available? Is there an online community to share knowledge with?

Faster data integration
Different groups across your organization can use AWS Glue to work together on data integration tasks, including extraction, cleaning, normalization, combining, loading, and running scalable ETL workflows. This way, you reduce the time it takes to analyze your data and put it to use from months to minutes.
Automate your data integration at scale
AWS Glue automates much of the effort required for data integration. AWS Glue crawls your data sources, identifies data formats, and suggests schemas to store your data. It automatically generates the code to run your data transformations and loading processes.
No servers to manage
AWS Glue runs in a serverless environment. There is no infrastructure to manage, and AWS Glue provisions, configures, and scales the resources required to run your data integration jobs. You pay only for the resources your jobs use while running.
Build event-driven ETL (extract, transform, and load) pipelines
AWS Glue can run your ETL jobs as new data arrives. For example, you can use an AWS Lambda function to trigger your ETL jobs to run as soon as new data becomes available in Amazon S3. You can also register this new dataset in the AWS Glue Data Catalog as part of your ETL jobs.
Create a unified catalog to find data across multiple data stores
You can use the AWS Glue Data Catalog to quickly discover and search across multiple AWS data sets without moving the data. Once the data is cataloged, it is immediately available for search and query using Amazon Athena, Amazon EMR, and Amazon Redshift Spectrum.
Create, run, and monitor ETL jobs without coding
AWS Glue Studio makes it easy to visually create, run, and monitor AWS Glue ETL jobs. You can compose ETL jobs that move and transform data using a drag-and-drop editor, and AWS Glue automatically generates the code.
