Data Contracts for SaaS Developers with Benn Stancil
The Thanksgiving break gives me enough time to catch up on a few podcasts. I'm a fan of the "SaaS Developer Community" podcast and Benn's writing, and I can't miss any conversation about Data Contracts.😎
My thoughts on this conversation, Benn captured very well the overall goal of the Data Contract and the skepticism around it. I have a long list of thoughts on this conversation, which might need a blog post on its own. I want to address one comment in the conversation.
“Developer’s Job is to ship the application code, not to make your dashboard looks good”
I agree that shipping the application code is the priority. But What is an “Application Code”? Let’s take an example of Slack features, “Compose a DM,” Channel Selection," Invite Members,” or “Invite Reminder”? Machine Learning powers every application feature listed above. Maybe Slack is 1% of the company implementing data engineering effectively to drive the product feature, but that is the point of implementing data contract and shifting left for an efficient data creation process.
If you think Data is only for unknown dashboards & back office needs, and data is not part of your product strategy, Sure, you don’t need Data Contract. But if you want to be that 1% of the company that differentiates the product experience and business operation with data, you need to focus on implementing Data Contracts.
Ian Macomber: Data Systems Tend Towards Production
I've seen many data predictions for successive years, but I'm always a fan of folks writing a look back at what happened in the industry to light up the future trend. Possibly one of the best reads I have had recently in Data Engineering, the author highlights three emerging patterns in Data engineering.
Systems Tend Towards Production
Systems Tend Towards Blind Federation
Systems Tend Towards Layerinitis

Meta AI: CICERO - An AI agent that negotiates, persuades, and cooperates with people
Did Meta successfully privatize world peace? 🤔
Meta writes about CICERO – the first AI to achieve human-level performance in the popular strategy game Diplomacy. CICERO demonstrated this by playing on webDiplomacy.net, an online version of the game. CICERO achieved more than double the average score of the human players and ranked in the top 10 percent of participants who played more than one game!!!

Sponsored: It’s Time for the Headless CDP
In this piece RudderStack CEO, Soumyadeb Mitra, makes the case for a new approach to the customer data platform—the headless CDP. He defines the headless CDP as a tool with open architecture, purpose built for data and engineering teams, that makes it easy to collect customer data from every source, build your customer 360 in your own warehouse, then make that Data available to your entire stack.

Becket Qin: Apache Flink SQL - Past, Present, and Future
Flink SQL made significant advancements in unifying the batch and the real-time computation. The blog captures the history of Flink SQL, its current state, and the challenges ahead of it. The stream-stream join is still expensive to operate; I’m excited to see the future progress of Flink SQL and how it can simplify operating streaming infrastructure.

LINE Engineering: A story of introducing data lineage into LINE's large-scale data platform
I thought Apache Atlas was largely forgotten at this stage; Line writes an exciting blog about its usage of Apache Atlas for data lineage. Too many data lineage visualizations can also confuse the users, and it is exciting that the Line data team highlighted the edge case and how it solved it.

Adrian Bednarz: DBT repository — to split or not to split?
Should we keep dbt monorepo in an organization or split it as multiple repos? The build systems like Bazel and Pants encourage monorepo, but that comes with operation and implementation costs. The author narrates how the dbt package helps to minimize code duplication and encourages multi-repo patterns.

Nic Crane: Type inference in readr and arrow
Every engineer has their own horror stories about their work with CSV files. We can write N number of blogs on Why You Don’t Want to Use CSV Files, But CSV format is widely used in data science and the simple human-readable format that is widely known and understood. The simplicity of CSV is its drawback; one such drawback is the lack of a type system. The author narrates how Apache Arrow infers types while reading the CSV file.
