  val env: StreamExecutionEnvironment = StreamExecutionEnvironment.getExecutionEnvironment
//  env.setStreamTimeCharacteristic(TimeCharacteristic.EventTime)

  val igniteSink = new IgniteSink[java.util.Map[String, String]]("testCache", "ignite-test.xml")
  igniteSink.setAllowOverwrite(true)
  igniteSink.setAutoFlushFrequency(10)
//  igniteSink.open(new Configuration)

  val igniteSink2 = new IgniteSink[java.util.Map[String, String]]("testCache2", "ignite-test.xml")

  igniteSink3.setAllowOverwrite(true)
  igniteSink3.setAutoFlushFrequency(10)
//  igniteSink3.open(new Configuration)

  val source = env.fromCollection(
    Array(
      Map("key1" -> "hello1"),

  source
    .filter(v => v.containsKey("key1"))

    .addSink(igniteSink)
      .name("sink1")
