DruidBeams

Builds Beams or Finagle services that send events to the Druid indexing service.

val curator = CuratorFrameworkFactory.newClient("localhost:2181", new BoundedExponentialBackoffRetry(100, 30000, 30))
curator.start()
val dataSource = "foo"
val dimensions = Seq("bar")
val aggregators = Seq(new LongSumAggregatorFactory("baz", "baz"))
val sender = DruidBeams
  .builder[Map[String, Any]](eventMap => new DateTime(eventMap("timestamp")))
  .curator(curator)
  .discoveryPath("/test/discovery")
  .location(DruidLocation(new DruidEnvironment("druid:local:indexer", "druid:local:firehose:%s"), dataSource))
  .rollup(DruidRollup(dimensions, aggregators, QueryGranularities.MINUTE))
  .tuning(new ClusteredBeamTuning(Granularity.HOUR, 10.minutes, 1, 1))
  .buildTranquilizer()
val future = sender.send(Map("timestamp" -> "2010-01-02T03:04:05.678Z", "bar" -> "hey", "baz" -> 3))
println("result = %s" format Await.result(future))

Your event type (in this case, Map[String, Any]) must be serializable via Jackson to JSON that Druid can understand. If Jackson is not an appropriate choice, you can provide an ObjectWriter via .objectWriter(...).

Start a builder for a custom type based on a particular Tranquility dataSourceConfig.
Start a builder for a custom type based on a particular Tranquility dataSourceConfig. Not all of the realtime spec in the config is used, but we do translate as much as possible into DruidBeams configurations. The builder generated by this method will already have a curatorFactory, tuning, druidTuning, location, rollup, objectWriter, timestampSpec, partitions, replicants, and druidBeamConfig set.
