WANTEDs

NOTE: function transformer

Possible inputs

1. streamlit code
   • sync & can work in any thread
   • sync & expects a ScriptThread
   • (AFAIK streamlit has no async API)
2. user code, including libs
   • sync
     • CPU intensive -> worker? (maybe process worker)
     • IO wait -> run in worker thread, reape as cf.Future or Awaitable
   • async
     • CPU intensive -> run in a different loop won't help
     • IO wait: not a problem

Function transformers

1. run sync function in worker thread AND pass ScriptContext
2. run sync function in worker thread AND get an Awaitable to not block as

WANT: lifetime signals

1. PageRunSignal a signal variable to capture 'page is running'
2. SessionSignal a signal variable to capture 'page is running'

concepts

concurrent.future

cf.Task

asyncio
