> {code:java}
> import org.apache.spark.storage.StorageLevel
> val df = spark.range(0, 1000000, 1, 5).map(l => (l, l))
> val ee = df.select($"_1".as("src"), $"_2".as("dst"))
> .persist(StorageLevel.MEMORY_AND_DISK)
> ee.count()
> val minNbrs1 = ee
> .groupBy("src").agg(min(col("dst")).as("min_number"))
> .persist(StorageLevel.MEMORY_AND_DISK)
> val join = ee.join(minNbrs1, "src")
> join.count(){code}
