About this Episode


Despite the best efforts of data engineers, data is as messy as the real world. Entity resolution and fuzzy matching are powerful utilities for cleaning up data from disconnected sources, but it has typically required custom development and training machine learning models. Sonal Goyal created and open-sourced Zingg as a generalized tool for data mastering and entity resolution to reduce the effort involved in adopting those practices. In this episode she shares the story behind the project, the details of how it is implemented, and how you can use it for your own data projects.


  • Hello and welcome to the Data Engineering Podcast, the show about modern data management
  • When you’re ready to build your next pipeline, or want to test out the projects you hear about on the show, you’ll need somewhere to deploy it, so check out our friends at Linode. With their new managed database service you can launch a production ready MySQL, Postgres, or MongoDB cluster in minutes, with automated backups, 40 Gbps connections from your application hosts, and high throughput SSDs. Go to today and get a $100 credit to launch a database, create a Kubernetes cluster, or take advantage of all of their other services. And don’t forget to thank them for their continued support of this show! RudderStack helps you build a customer data platform on your warehouse or data lake. Instead of trapping data in a black box, they enable you to easily collect customer data from the entire stack and build an identity graph on your warehouse, giving you full visibility and control. Their SDKs make event streaming from any app or website easy, and their extensive library of integrations enable you to automatically send data to hundreds of downstream tools. Sign up free at
  • Modern data teams are dealing with a lot of complexity in their data pipelines and analytical code. Monitoring data quality, tracing incidents, and testing changes can be daunting and often takes hours to days or even weeks. By the time errors have made their way into production, it’s often too late and damage is done. Datafold built automated regression testing to help data and analytics engineers deal with data quality in their pull requests. Datafold shows how a change in SQL code affects your data, both on a statistical level and down to individual rows and values before it gets merged to production. No more shipping and praying, you can now know exactly what will change in your database! Datafold integrates with all major data warehouses as well as frameworks such as Airflow & dbt and seamlessly plugs into CI workflows. Visit today to book a demo with Datafold.
  • Data teams are increasingly under pressure to deliver. According to a recent survey by, 95% in fact reported being at or over capacity. With 72% of data experts reporting demands on their team going up faster than they can hire, it’s no surprise they are increasingly turning to automation. In fact, while only 3.5% report having current investments in automation, 85% of data teams plan on investing in automation in the next 12 months. 85%!!! That’s where our friends at come in. The Ascend Data Automation Cloud provides a unified platform for data ingestion, transformation, orchestration, and observability. Ascend users love its declarative pipelines, powerful SDK, elegant UI, and extensible plug-in architecture, as well as its support for Python, SQL, Scala, and Java. Ascend automates workloads on Snowflake, Databricks, BigQuery, and open source Spark, and can be deployed in AWS, Azure, or GCP. Go to and sign up for a free trial.

  • Your host is Tobias Macey and today I’m interviewing Sonal Goyal about Zingg, an open source entity resolution framework for data engineers


  • Introduction
  • How did you get involved in the area of data management?
  • Can you describe what Zingg is and the story behind it?
  • Who is the target audience for Zingg?
    • How has that informed your efforts in the development and release of the project?
  • What are the use cases where entity resolution is helpful or necessary in a data engineering context?
  • What are the range of options that are available for teams to implement entity/identity resolution in their data?
    • What was your motivation for creating an open source solution for this use case?
    • Why do you think there has not been a compelling open source and generalized solution previously?
  • Can you describe how Zingg is implemented?
    • How have the design and goals shifted since you started working on the project?
  • What does the installation and integration process look like for Zingg?
  • Once you have Zingg configured, what is the workflow for a data engineer or analyst?
  • What are the extension/customization options for someone using Zingg in their environment?
  • What are the most interesting, innovative, or unexpected ways that you have seen Zingg used?
  • What are the most interesting, unexpected, or challenging lessons that you have learned while working on Zingg?
  • When is Zingg the wrong choice?
  • What do you have planned for the future of Zingg?
