Build Real Time Applications With Operational Simplicity Using Dozer
Data Engineering Podcast
Dozer: A Self-Contained Tool for Data Integration
Dozer is a self-contained tool. We didn't want to have a dependency to external tools like Kafka or distributed key values store, so you wanted to keep it very simple. It's all implemented in Rust that gives us the performance. After the ingestion, we fundamentally have a streaming SQL engine that has been built up and built from the ground up. This allows us to basically allow the user to create a model by joining sources aggregating then will be stored in the caching layer.

Summary
Real-time data processing has steadily been gaining adoption due to advances in the accessibility of the technologies involved. Despite that, it is still a complex set of capabilities. To bring streaming data in reach of application engineers Matteo Pelati helped to create Dozer. In this episode he explains how investing in high performance and operationally simplified streaming with a familiar API can yield significant benefits for software and data teams together.

- Your host is Tobias Macey and today I'm interviewing Matteo Pelati about Dozer, an open source engine that includes data ingestion, transformation, and API generation for real-time sources
Interview
- Introduction
- How did you get involved in the area of data management?
- Can you describe what Dozer is and the story behind it?
- What was your decision process for building Dozer as open source?
- As you note in the documentation, Dozer has overlap with a number of technologies that are aimed at different use cases. What was missing from each of them and the center of their Venn diagram that prompted you to build Dozer?
- In addition to working in an interesting technological cross-section, you are also targeting a disparate group of personas. Who are you building Dozer for and what were the motivations for that vision?
- What are the different use cases that you are focused on supporting?
- What are the features of Dozer that enable engineers to address those uses, and what makes it preferable to existing alternative approaches?
- Can you describe how Dozer is implemented?
- How have the design and goals of the platform changed since you first started working on it?
- What are the architectural "-ilities" that you are trying to optimize for?
- What is involved in getting Dozer deployed and integrated into an existing application/data infrastructure?
- How can teams who are using Dozer extend/integrate with Dozer?
- What does the development/deployment workflow look like for teams who are building on top of Dozer?
- What is your governance model for Dozer and balancing the open source project against your business goals?
- What are the most interesting, innovative, or unexpected ways that you have seen Dozer used?
- What are the most interesting, unexpected, or challenging lessons that you have learned while working on Dozer?
- When is Dozer the wrong choice?
- What do you have planned for the future of Dozer?
