No, you haven't missed anything, but I think the convenience APIs
we're discussing in this thread are what you need, rather than
async/await.
Specifically, your main application would remain synchronous, but the
event loop could be used to run selected operations in a background
thread:
def business_new():
future1 = asyncio.call_async(open('big.file').read)
future2 = asyncio.call_async(open('huge.file').read)
content1 = asyncio.wait_for_result(future1)
content2 = asyncio.wait_for_result(future2)
return content1 + content2
Cheers,
Nick.
