Optionalparams: FileDownloadParameters & { highWaterMark?: number }File download parameters
OptionalhighWaterMark?: numberIf passed, the maximum number of bytes that can be buffered in the stream.
If the consumer isn't keeping up, the stream will pause until the buffer is below this limit.
Note that this parameter is not guaranteed to be strictly the maximum number of bytes
buffered at once, since the underlying download is parallelized, and is treated merely as a hint.
The actual number of bytes buffered at once can be as much as partSize * numWorkers
