Data Quality and Data Observability - The Core Aspects of Data Discovery

Summary

This podcast started almost exactly six years ago, and the technology landscape was much different than it is now. In that time there have been a number of generational shifts in how data engineering is done. In this episode I reflect on some of the major themes and take a brief look forward at some of the upcoming changes.

Announcements

• Hello and welcome to the Data Engineering Podcast, the show about modern data management
• Your host is Tobias Macey and today I'm reflecting on the major trends in data engineering over the past 6 years

Interview

• Introduction
• 6 years of running the Data Engineering Podcast
• Around the first time that data engineering was discussed as a role
  • Followed on from hype about "data science"
• Hadoop era
• Streaming
• Lambda and Kappa architectures
  • Not really referenced anymore
• "Big Data" era of capture everything has shifted to focusing on data that presents value
  • Regulatory environment increases risk, better tools introduce more capability to understand what data is useful
• Data catalogs
  • Amundsen and Alation
• Orchestration engine
  • Oozie, etc. -> Airflow and Luigi -> Dagster, Prefect, Lyft, etc.
  • Orchestration is now a part of most vertical tools
• Cloud data warehouses
• Data lakes
• DataOps and MLOps
• Data quality to data observability
• Metadata for everything
  • Data catalog -> data discovery -> active metadata
• Business intelligence
  • Read only reports to metric/semantic layers
  • Embedded analytics and data APIs
• Rise of ELT
  • dbt
  • Corresponding introduction of reverse ETL
• What are the most interesting, unexpected, or challenging lessons that you have learned while working on running the podcast?
• What do you have planned for the future of the podcast?

Parting Question

• From your perspective, what is the biggest gap in the tooling or technology for data management today?
