I suppose, if you want to use in in closed source version.
However, what is interesting in the Synapse approach, is that you keep 
Mnesia as is but change the backend. Depending on your needs you can use 
different backends.
This is interesting because you will not use the same backend for 
real-time in-ram database or for huge on disk storage.
You could also decide to choose your backend depending on your licensing 

This architecture looks like MySQL one:

Note that on this schema, the RAM backend for MySQL is Network DataBase 
(NDB), which use to be an Ericsson product.
