------------------------------------
Ok. But then should we rename the other one as invertLong ?
> [storage implementation] app id as string in row keys can cause incorrect
> ordering

> 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.
