gt also title Do we need dependency information at all for concurrency and remoting I m thinking it may be more descriptive and focused to say gt Dependency inference fine grained caching without the boilerplate

hundreds-father-404 · Answer

Note that lots of folks don t know what remoting means I think this suggested title is more accessible that you can easily see what the article is gonna be about Also nit to lowercase the inference

witty-crayon-22786 · Answer

yep you need it for concurrency because you need to know what depends on what for example if we actually partitioned mypy by file we d be able to run dozens of instances at once because we know which files depend on which other files

witty-crayon-22786 · Answer

if you view the JSON cache as the output of compilation then you can think of mypy as a compiler and definitely the case for compilers in general

witty-crayon-22786 · Answer

and yes absolutely for remoting as well it s how you know what needs to be in the sandbox to run

witty-crayon-22786 · Answer

but i ll drop remoting
