Answer / Saurabh Kumar Gupta
In Spark Streaming, the level of parallelism refers to the number of streaming tasks that are executed at a given moment. This can be set using the `sparkStreaming.setNumStreamingExecutors()` and `sparkStreaming.setNumThreads()` methods. Increasing parallelism can improve performance but should be carefully managed as it consumes more resources.
