> Currently the app id is used in various places as part of row keys and in column names.
However, they are treated as strings for the most part. 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_100" will be considered *earlier* than "app_1234567890_99".
We should correct this.
