   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?
