One obvious bottleneck is the sequential processing. Since you are already
creating multiple streams, you can increase concurrency using
`spark.streaming.concurrentJobs`. You can set it as
`sparkConf.set("spark.streaming.concurrentJobs", "4");` [Check
this](https://stackoverflow.com/questions/34430636/spark-processing-multiple-kafka-topic-in-parallel)
On a side note, how are you handling deletes? Or you don't have deletes in
your DB?
