Question about streaming to memorymapped files
Hey, I'm looking into streaming table updates into a memory mapped file ( C++ )
I think I have everything I need ( MemoryMappedFile output streamer, RecordBatchStreamWriter ) but I don't understand how to properly create the memmap file. It looks like it requires you to preset a size to the file when you create it, but since ill be streaming I don't actually know how big a file im going to need...
Am I missing some other API point here? Any reason why size is required up front and the memmap doesn't auto-grow as needed?
Thanks in advance
