[sqlite] Can sqlite access storage system directly?

2014-04-04 Thread 김병준 
After spend quite long time search for regarding to use file I/O in
SQLite,
   
I've found that through the VFS layer is the only way go into the
kernel.
   
However I am wandering about if there is other method to detour
filesystem,
   
so that SQLite is directly interface with device driver layer.
   
I think there might be number of disadvantage if SQLite run without
   
filesystem help, but there will be performance gain. ( e.g. From not
using
   
Journaling and eliminate block I/O overhead.)
   
Is there anyone have tried it or know about method? 
 
   
it would very helpful at least tell me whether it is possible or not.
