Approach

This section contains guidelines used throughout the code base.

• Use asyncio everywhere. Isolate any code that needs to be blocking in a separate worker thread.

• Standardize naming. Sources, sinks, and steps are all functions with a suffix on the name indicating what type they are.

• Build off existing abstractions. Python already has async iterators which work well, and LangChain has Runnables. Avoid new core abstractions to improve interoperability.
