Controller

Overview

The Controller project is an infrastructure service that supports other OpenDaylight projects. It does not have user-facing features.

Behavior/Feature Changes

The default configuration of the Distributed Datastore has been changed to take advantage of the tell-based protocol which has been long in the works. This prevents the dreaded AskTimeoutException from being reported to applications. It also has much more modest requirements on native memory when coupled with Akka Artery.

The ask-based protocol remains a configurable option and will remain for at least one release, but its use should be avoided unless necessary.

New Features

There are no new features.

Deprecated and Removed Features

No deprecated or removed features.
