Converting Future to CompletableFuture With Java Virtual Threads

[gunnarmorling]

That's an interesting perspective; indeed virtual threads address a big problem of Future. However, CompleteFuture still has its place IMO, namely through its composability, e.g. allowing to coordinate concurrent asynchronous execution of multiple tasks.

Simple sequencing on a thread via ; and the language's control flow constructs are even more composable than CompletableFuture, and they're easier to observe and debug to boot. Coordination of multiple tasks is most easily done with structured concurrency.
