    In-RAM databases are orders of magnitude faster than disk based SQL
    engines. RAM is getting cheap enough that many databases, or at least
    the crucial part could be totally RAM-resident.

    You then have two problems:

    1. handling failures
    2. persisting/exporting the data.

    You could handle failures by having paired machines each running off a
    UPS running in tandem.

    you could handle the persistence problem by some sort of POD or export
    that runs in the background cycling through the objects, perhaps
    several minutes behind the changes, or by logging transactions that
    could later be replayed.

    Whatever your solution, you bundle it up so that it becomes as
    convenient to use as a POD or SQL database.
