Are we back to MongoDB -- no fsync() but webscale speed?

#42Off topic, but why is tokio still independent of the rust async runtime?
It seems pretty ubiquitous yet not a part of the core rust libs.

The same reason as ever. Not everyone wants to use the same runtime.

Sure, but now if my rust application isn't using tokio I have to include it as a new dependency because the author of this lib decided to use it as his async runtime?
I'm not trying to be pedantic, but this split over async runtimes was what originally turned me off of rust years ago and it still seems to be an issue.

This is surprisingly common, from what I can tell.

I'm using async on esp32 with embassy, for instance, where there's simply no room and no need for a runtime as complex as tokio.

Word choice matters. Defaults matter. People will go "well it says durable right here" and while arguably, yes, they should RTFM, it would still be great if tool-builders did not set the shotgun's default state to State::AT_FOOT. It would be nice if every paragraph of technical writing that I have to do need not be burdened by a thousand asterisks of "durable in this context means something other than durable".
>arguably, yes, they should RTFM Agreed. Good design is when the things do what you expect them to do without reading the manual, don't reuse wording with other meaning in the wrong way. That way if you do encounter nee wording, you know you should read the manual.
