ETL Part 3: Production (with capstone)
In this course data engineers optimize and automate Extract, Transform, Load (ETL) workloads using stream processing, job recovery strategies, and automation strategies like REST API integration. By the end of this course you will schedule highly optimized and robust ETL jobs, debugging problems along the way.
NOTE: This course is specific to the Databricks Unified Analytics Platform (based on Apache Spark™). While you might find it helpful for learning how to use Apache Spark in other environments, it does not teach you how to use Apache Spark in those environments.
You will see the following warning:
WARNING: This notebook was tested on DBR 6.2 but we found DBR 7.0. Using an untested DBR may yield unexpected results and/or various errors Please update your cluster configuration and/or download a newer version of this course before proceeding.
A new version of the courseware currently is not available but we encourage you to continue enjoying the course with a newer runtime
3-6 hours, 75% hands-on
The course is a series of six self-paced lessons available in both Scala and Python. A final capstone project involves refactoring a batch ETL job to a streaming pipeline. In the process, students run the workload as a job and monitor it. Each lesson includes hands-on exercises.
This course is intended to be run in a Databricks workspace. The course contains Databricks notebooks for both Azure Databricks and AWS Databricks; you can run the course on either platform.
Note: Access to a Databricks workspace is not part of your course purchase price. You are responsible for getting access to Databricks. See the FAQ for instructions on how to get access to an Databricks workspace.
Note: This course will not run on Databricks Community Edition.
