Dagster offers flexible code location management, allowing developers to organize their project in various ways. A single code location can work well for early-stage projects or smaller teams with a more general approach, while team-based locations are suitable for larger teams with different development cadences. Tool-based locations group code by function and dependencies, promoting clarity and clean boundaries between concerns like ingestion, transformation, and reporting. Dedicated code locations can be used to isolate critical pipelines or assets, allowing for fine-tuning, isolation, or control over specific sets of assets. Decoupling shared code, such as custom Dagster resources, utilities, or helpers, from specific asset definitions can also improve organization and management. Ultimately, there are no hard rules, and the best approach depends on the team's structure, workflows, and how the organization manages code.
