Structured Concurrency vs the Streams API

[Ron Pressler]

Hi.

Parallel streams are indeed structured, but they’re (currently) focused on pure processing and data parallelism, rather than “concurrency,” which often involves a lot of I/O, failure handling, and cancellation.

It is also true that the Stream API could be modified to implement some flavour of structued concurrency, and it is an idea that we’re thinking about.
