Last week, we held a live webinar—Databricks for Data Engineers—to provide an overview of the data engineering role, common challenges data engineers face while building ETL pipelines, and how Databricks can help data engineers easily build production-quality data pipelines with Apache Spark.

Prakash Chockalingam, product manager at Databricks, also gave a live demonstration of Databricks and features that data engineers would benefit from such as:

  • Advanced cluster management functionalities that suit any workload requirements.
  • The ability to interactively build an ETL pipeline via an integrated workspace.
  • Simplified troubleshooting of jobs with monitoring alerts.
  • Job scheduling with helpful features like alerting, custom retry policies, and parallel runs.
  • Notebook workflows which allow you to build multi-stage production Spark pipelines directly from Databricks notebooks.

The webinar is now accessible on-demand, and the slides used in the webinar are also downloadable as attachments to the webinar.

We have also answered the common questions raised by webinar viewers below. If you have additional questions, check out the Databricks Forum or the new documentation resource.
