Techcrunch: Astronomer ready for its next mission after Datakin acquisition, $213M Series C
It's been an eventful week at the Data Council conference in Austin. I plan to reflect on my experience later this week, so stay tuned. One of the big news on the conference day is that Astronomer acquired DataKin, the company behind the open-source Marquez project. I predicted the consolidation on data lineage and orchestration engines, but I never thought this would happen this fast.
Jon Loyens: How Should We Be Thinking about Data Lineage?
Why is data lineage so crucial in data management? The author gives an overview of what a comprehensive data lineage can bring into data management.

Pardis Noorzad: Challenges in data sharing and transfer
Buy vs. Build is always an ongoing architectural decision in an organization. I've seen folks underestimate the "cost to integrate" off-the-shelf solutions. The author captured the challenges in validating and integrating MLOps and DataOps products. I have written about the emerging patterns of data sharing in data engineering weekly [Omicron Paradigm: Architectural patterns for the Infinite Data Logistic]. It is an exciting data engineering challenge to solve.

Zan Armstrong: Stop aggregating away the signal in your data
Aggregation is the standard best practice for analyzing time series data, but it can create problems by stripping away crucial context. The author narrates the consequence of uninformed data aggregation.
But every time you aggregate, you make a decision about which features of your data matter and which ones you are willing to drop. Informed aggregation simplifies and prioritizes. Uninformed aggregation means you’ll never know what insights you lost.

Lyft: Orchestrating Data Pipelines at Lyft - comparing Flyte and Airflow
Last week we saw Spotify moving away from Luigi to Flyte. Lyft writes about its incubation of Flyte and the difference between Airflow. However, I can't stop wondering why a new system instead of adding the features in Airflow! Nonetheless, it is excellent to see event-driven dependency management rather than the polling approach in Airflow.

Miro: Miro Data Engineering team’s journey to monitoring
I've not seen many engineering blogs talking about the developer workflow after an alert or incident in the data pipeline. DataOps is my favorite part of data engineering, and glad to see Miro's developer workflow of DataOps.
