And never forget the filesystem! Allows highly efficient concurrent
writes, optimized caching at the kernel level, has a nice hierarchical
structure and there are many tools to work with it! In situations where
you have high write rates but the write operations are decoupled to a
degree that no file locking is required (for instance session info) then
an FS solution can be *very* fast.
