Hi Vida, I am writing to a DB -- or trying to :).
I believe the best practice for this (you can search the mailing list archives) is to do a combination of mapPartitions and use a grouped iterator. Look at this thread, esp. the comment from A. Boisvert and Matei's comment above it: https://groups.google.com/forum/#!topic/spark-users/LUb7ZysYp2k Basically the short story is that you want to open as few connections as possible but write more than 1 insert at a time. -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/Save-an-RDD-to-a-SQL-Database-tp11516p11549.html Sent from the Apache Spark User List mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@spark.apache.org For additional commands, e-mail: user-h...@spark.apache.org
