[ClSlaid]

Can we use blocking IO functions in local fs services to implement Accessor's asynchronous functions directly? What is the drawback of our current non-blocking API?

[Xuanwo]

Can we just use blocking IO functions in local fs services if they are much faster than the tokio::fs functions?

We can't run blocking IO functions inside the async context. We need to let the local thread pool execute them and use mio to listen to the events. If we do so, congrats, we are building tokio::fs again!

This is a good question, I will add into RFC.

[ClSlaid]

Keeping 2 sets of APIs is prefered.
