Hey 🙂 Quick stupid question. When you’re in a coroutine and call a blocking java function (like a guava future’s get method) does it block the whole thread? I’d say yes but then how do you handle libraries that use that kind of future internally?

Yes, there is no magic that transforms blocking calls into non blocking ones in Kotlin.

<http://Dispatchers.IO|Dispatchers.IO>

is the one to use with blocking calls
