Detailed Description": "Dagster is a modern, open-source data orchestrator designed for the entire development lifecycle of data applications. Unlike traditional task-based orchestrators, Dagster is built around the concept of 'software-defined assets,' which are declarative representations of the data assets that a pipeline produces. This asset-centric approach provides a unified view of data dependencies, improves data lineage, and makes pipelines easier to understand, test, and maintain. Dagster comes with a rich web interface (Dagit) for visualizing, monitoring, and debugging pipelines, and it emphasizes local development and testing to catch errors before deployment. It aims to provide a single pane of glass for all data assets, from raw data to machine learning models.
