How Schema RDD can help in inserting data into my Database in Apache Spark


How Schema RDD can help in persist data into any Database in Apache Spark and also it is available in new version1.4.1 or not?
Convert your RDD to DataFrame and write into Database,
val df = myrdd.toDF()
df.write.jdbc(…)
I ran into same spot and referred below link,
http://www.sparkexpert.com/2015/04/17/save-apache-spark-dataframe-to-database/
Whatever is your database, use it's api as you use in simple java, scala or python and perform foreach transformation to the schema RDD, you can't insert the schema RDD automatically to your database, you have to do mapping in spark.
