Thanks for asking!

It's both. The OCR part is ofc CPU bound, but the entire text extraction involves reading files, or writing and then reading files.

Without async, these simply block.

As for efficiency - if you're working in an async application context you have to "asyncify" these operations or suffer the consequences.

in that case, what’s the deal with extract_bytes being async? i’m not incredibly familiar with python, but i’d expect a “byte string” to be in memory.

You still need to write it to file to process it via pandoc/tesseract etc.

There are alternative options to tesseract ofc.

This sounds... I guess Pythonic? Sheesh.
