Predef

object Predef

Aliases for types and objects commonly used in Summingbird jobs. Importing these makes it easier to define jobs:

import com.twitter.summingbird.Predef._

class MyJob(env: Env) extends AbstractJob {
  import MyJob._  // assumed to hold flatmapper and sources

implicit val batcher: Batcher = Batcher.ofHours(2)
// Now, job creation is easy!

}
