Twitter’s com.twitter.util.Future is similar to, but predates, Scala’s scala.concurrent.Future and as such they are not directly compatible (e.g. support for continuation-local variables and interruptibility).. You can use the Twitter Bijection library to transform one into the other, or use a small bit of code shown below to Twitter futures are more explicit about where computations are executed than the Scala standard library futures. This approach has several advantages over the standard library’s future API. For one thing, it keeps method signatures simpler, since there’s not an implicit ExecutionContext that has to be passed around everywhere. Effective Scala contains a section discussing futures; As of Scala 2.10, the Scala standard library has its own futures implementation and API, described here. Note that this is largely similar to the API used in Finagle (com.twitter.util.Future), but there are still some naming differences. With Scala's Futures, the information only flows in one direction, with Twitter's Future, you can notify a producer of some information (not necessarily a cancellation). In practice, it's used in Finagle to propagate the cancellation of a RPC.

The predicates scala.util.control.NonFatal — or Twitter’s version com.twitter.util.NonFatal — should be used to identify exceptions which should be returned as a Future.exception. Collections The subject of concurrent collections is fraught with opinions, subtleties, dogma and FUD.

Combining Futures (Twitter) and Either in Scala. Ask Question Asked 6 years, 3 months ago. Active 6 years, 3 months ago. Viewed 1k times 4. 1. We use Twitter futures (as part of the Finagle stack) and I don't like the concept of using (business) exceptions to control the flow of our application, because exceptions don't show up in method signatures. So I had the idea to use Future[Either[A,B I'm using twitter util futures in my project. I want to add logging to trace a request through the components using MDC. I couldn't find a good way to add that for twitter futures as there is no

Futures. Finagle uses com.twitter.util.Future 1 to encode delayed operations. A Future is a handle for a value not yet available. Don’t confuse com.twitter.util.Future with scala.concurrent.Future or java.util.concurrent.Future! 2 If you study type systems and/or category theory, you’ll be glad to learn that flatMap is equivalent to a
