Set off an AWS Glue DataBrew job primarily based on an occasion generated from one other DataBrew job


Organizations as we speak have steady incoming information, and analyzing this information in a well timed trend is changing into a typical requirement for information analytics and machine studying (ML) use instances. As a part of this, you want clear information as a way to acquire insights that may allow enterprises to get probably the most out of their information for enterprise development and profitability. Now you can use AWS Glue DataBrew, a visible information preparation instrument that makes it simple to remodel and put together datasets for analytics and ML workloads.

As we construct these information analytics pipelines, we are able to decouple the roles by constructing event-driven analytics and ML workflow pipelines. On this submit, we stroll by means of find out how to set off a DataBrew job mechanically on an occasion generated from one other DataBrew job utilizing Amazon EventBridge and AWS Step Features.

Overview of resolution

The next diagram illustrates the structure of the answer. We use AWS CloudFormation to deploy an EventBridge rule, an Amazon Easy Queue Service (Amazon SQS) queue, and Step Features assets to set off the second DataBrew job.

The steps on this resolution are as follows:

  1. Import your dataset to Amazon Easy Storage Service (Amazon S3).
  2. DataBrew queries the information from Amazon S3 by making a recipe and performing transformations.
  3. The primary DataBrew recipe job writes the output to an S3 bucket.
  4. When the primary recipe job is full, it triggers an EventBridge occasion.
  5. A Step Features state machine is invoked primarily based on the occasion, which in flip invokes the second DataBrew recipe job for additional processing.
  6. The occasion is delivered to the dead-letter queue if the rule in EventBridge can’t invoke the state machine efficiently.
  7. DataBrew queries information from an S3 bucket by making a recipe and performing transformations.
  8. The second DataBrew recipe job writes the output to the identical S3 bucket.


To make use of this resolution, you want the next conditions:

Load the dataset into Amazon S3

For this submit, we use the Credit score Card prospects pattern dataset from Kaggle. This information consists of 10,000 prospects, together with their age, wage, marital standing, bank card restrict, bank card class, and extra. Obtain the pattern dataset and observe the directions. We suggest creating all of your assets in the identical account and Area.

Create a DataBrew venture

To create a DataBrew venture, full the next steps:

  1. On the DataBrew console, select Initiatives and select Create venture.
  2. For Challenge title, enter marketing-campaign-project-1.
  3. For Choose a dataset, choose New dataset.
  4. Underneath Information lake/information retailer, select Amazon S3.
  5. For Enter your supply from S3, enter the S3 path of the pattern dataset.
  6. Choose the dataset CSV file.
  7. Underneath Permissions, for Position title, select an present IAM position created in the course of the conditions or create a brand new position.
  8. For New IAM position suffix, enter a suffix.
  9. Select Create venture.

After the venture is opened, a DataBrew interactive session is created. DataBrew retrieves pattern information primarily based in your sampling configuration choice.

Create the DataBrew jobs

Now we are able to create the recipe jobs.

  1. On the DataBrew console, within the navigation pane, select Initiatives.
  2. On the Initiatives web page, choose the venture marketing-campaign-project-1.
  3. Select Open venture and select Add step.
  4. On this step, we select Delete to drop the pointless columns from our dataset that aren’t required for this train.

You possibly can select from over 250 built-in capabilities to merge, pivot, and transpose the information with out writing code.

  1. Choose the columns to delete and select Apply.
  2. Select Create job.
  3. For Job title, enter marketing-campaign-job1.
  4. Underneath Job output settings¸ for File kind, select your remaining storage format (for this submit, we select CSV).
  5. For S3 location, enter your remaining S3 output bucket path.
  6. Underneath Settings, for File output storage, choose Change output information for every job run.
  7. Select Save.
  8. Underneath Permissions, for Position title¸ select an present position created in the course of the conditions or create a brand new position.
  9. Select Create job.

Now we repeat the identical steps to create one other DataBrew venture and DataBrew job.

  1. For this submit, I named the second venture marketing-campaign-project2 and named the job marketing-campaign-job2.
  2. While you create the brand new venture, this time use the job1 output file location as the brand new dataset.
  3. For this job, we deselect Unknown and Uneducated within the Education_Level column.

Deploy your assets utilizing CloudFormation

For a fast begin of this resolution, we deploy the assets with a CloudFormation stack. The stack creates the EventBridge rule, SQS queue, and Step Features state machine in your account to set off the second DataBrew job when the primary job runs efficiently.

  1. Select Launch Stack:
  2. For DataBrew supply job title, enter marketing-campaign-job1.
  3. For DataBrew goal job title, enter marketing-campaign-job2.
  4. For each IAM position configurations, make the next selection:
    1. If you happen to select Create a brand new Position, the stack mechanically creates a task for you.
    2. If you happen to select Connect an present IAM position, it’s essential to populate the IAM position ARN manually within the following subject or else the stack creation fails.
  5. Select Subsequent.
  6. Choose the 2 acknowledgement examine packing containers.
  7. Select Create stack.

Check the answer

To check the answer, full the next steps:

  1. On the DataBrew console, select Jobs.
  2. Choose the job marketing-campaign-job1 and select Run job.

This motion mechanically triggers the second job, marketing-campaign-job2, through EventBridge and Step Features.

  1. When each jobs are full, open the output hyperlink for marketing-campaign-job2.

You’re redirected to the Amazon S3 console to entry the output file.

On this resolution, we created a workflow that required minimal code. The primary job triggers the second job, and each jobs ship the reworked information information to Amazon S3.

Clear up

To keep away from incurring future fees, delete all of the assets created throughout this walkthrough:

  • IAM roles
  • DataBrew initiatives and their related recipe jobs
  • S3 bucket
  • CloudFormation stack


On this submit, we walked by means of find out how to use DataBrew together with EventBridge and Step Features to run a DataBrew job that mechanically triggers one other DataBrew job. We encourage you to make use of this sample for event-driven pipelines the place you’ll be able to construct sequence jobs to run a number of jobs at the side of different jobs.
