Add dagster

What is this Python project?

Dagster is a job orchestration framework that is used to build data assets. It is a great tool, works on multiple platforms, and is very easy to set it up. It has a lot of useful features, such as:

• Managing data assets with code, building python-based data jobs to load, transfer, and transform data
• Integrates with dbt and provides a user interface to run dbt models
• Provides a UI to monitor jobs, debug runs, inspect assets, or even launch backfills
• Multiplatform - works with Windows and Mac by just installing from pip (no other dependencies)
• It has multiple executors to run tasks, including in-process, multi-process, Dask, Celery, Docker, and Kubernetes.

What's the difference between this Python project and similar ones?

Enumerate comparisons.

• One great comparison for dagster is Airflow - but Dagster concentrates more on orchestrating data assets, including table materializations, etc
• It is not just a scheduler, but a framework to build jobs using Dagster API
