Update for posterity, so once again I solved the problem shortly after posting to the mailing list. So updateStateByKey uses the default partitioner, which in my case seemed like it was set to one.
Changing my call from .updateStateByKey[Long](updateFn) -> .updateStateByKey[Long](updateFn, numPartitions) resolved it for me. -- View this message in context: http://apache-spark-user-list.1001560.n3.nabble.com/Spark-Streaming-No-parallelism-in-writing-to-database-MySQL-tp15174p15182.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
