On the contrary--it's not obvious that it is an ideal fit for a WAL. A
ram disk like this is optimized for highly random access applications.
The WAL is a single sequential writer. If you're in the kind of market
that needs a really high performance WAL you'd be much better served by
putting a big NVRAM cache in front of a fast disk array than by buying a
toy like this.
