In databricks docs it says 

"If you use maxBytesPerTrigger in conjunction with maxFilesPerTrigger, the micro-batch processes data until either the maxFilesPerTrigger or maxBytesPerTrigger limit is reached."

But based on the source code this is not true.

val maxBytesPerTrigger: Option[Long] = parameters.get("maxBytesPerTrigger").map { str =>
    Try(str.toLong).toOption.filter(_ > 0).map(op =>
      if (maxFilesPerTrigger.nonEmpty) {
        throw new IllegalArgumentException(
          "Options 'maxFilesPerTrigger' and 'maxBytesPerTrigger' " +
            "can't be both set at the same time")
      } else op
    ).getOrElse {
      throw new IllegalArgumentException(
        s"Invalid value '$str' for option 'maxBytesPerTrigger', must be a positive integer")
    }
  }

Am i missing something here?
