Mesos State Backed Collections
Persistent collection types backed by implementations of the Mesos state API.
API Usage Example (work-in-progress)
import akka.util.ByteString
import mesosphere.util.mesos.state.{ PersistentSet, WrappedState }
import org.apache.mesos.state.AbstractState
import scala.concurrent.Future
val state: AbstractState = // ...
case class Person(name: String, age: Int)
val personFormatter = new Formatter[Person] {
def read(bytes: ByteString): Person = // ...
def write(value: Person): ByteString = // ...
}
val wrappedState = WrappedState(state, formatter)
val people: PersistentSet[Person] = wrappedState.makeSet("people")
people ++= Seq(Person("Wayne", 23), Person("Garth", 24))
val result: Future[Try[Unit]]] = people.commit()
