Since you pasted much code, next time open an issue, where the code
formatting can be retained, as in emails it's impossible to read the
code.

It is ok to read the 10 MiB all at once and send it in one call to
Stream.data() -- like you are doing in the first approach.
However, on the receiving side, you will likely receive multiple
DataFrames that when they are re-assembled will produce the original
whole content.
If I read your code correctly, on the server side you open a file,
save a chunk of bytes, then close the file, so the file will
eventually only have the last chunk in it.
You have to open the file in append mode, or keep it open until you
see the last DataFrame.
In your second approach, it is ok to read the source bytes in chunks,
but don't rely on available().
You should read a source chunk and send it as a non-last DataFrame,
until you read -1.
When you read -1, you send an empty, last, DataFrame.
