Description
Hello boost developer's
I use managed_mapped_file for my project to create shared data structure and it is very good solution and simple to use. But i have a problem for big data & big query. I nead to have Huge page memory map file for better performance. I was check source code and see where is pass flag to mmap function in linux but no way to pass this flag from managed_mapped_file.
I can to edit source to pass this argument but i hoop to this change added to boost source for all of developer use .
source class hierarchy:
managed_mapped_file
basic_managed_mapped_file
mfile_open_or_create
managed_open_or_create_impl::priv_open_or_create
-> mapped_region (...,addr/*, map_options*/);
source file hierarchy:
