This guide shows you how to build a Data Pipeline with Apache Airflow that manages DBT model transformations and conducts data analysis with Snowpark, all in a single DAG. This project aims to orchestrate a data pipleine using SNowflake operators in Airflow. That’s not a hard and fast rule, I’m sure there are cases where spark is the only way to go (streaming for example), but for a basic set of business analytic use cases snowflake is enough. By integrating these tools, we aim to create a seamless flow for extracting, transforming, and loading data. They combine the features of data warehouses and data lakes to provide the best of both worlds in data storage and computing. (See Working With Compute Pools). Provide details and share your research! But avoid . How does Snowflake integrate with Airflow? Snowflake can be integrated with Airflow using the Snowflake operator, which allows for seamless data insertion, extraction, and processing tasks within the Airflow DAG. This works perfect with full loads because there aren't large Here's what we see in top snowflake developer resumes. 1 AWS MWAA - Airflow - Load Connections. You would need Since Airflow 2.
