> Currently the app id is used in various places as part of row keys. However, currently
they are treated as strings. This will cause a problem with ordering when the id portion of
the app id rolls over to the next digit.
> For example, "app_1234567890_10000" will be considered *earlier* than "app_1234567890_9999".
We should correct this.
