Hi, with Solids. Do we often import a whole script and run it within a solid ? I'm trying to understand how we avoid a really big script with lots of solid definitions?

You can save solids in solids folder, pipelines in pipelines folder, etc. Then do the usual imports. Here are a couple project examples: https://github.com/AntonFriberg/dagster-project-example https://github.com/dagster-io/dagster/tree/master/examples/hacker_news

That's awesome! Thanks so much.
