Theoretically there is no maximum acceptable value, but in practice this is determined by the SPARQL engine you use and the programming environment in which it runs. Your example is in Java, the number set here is 2^31 which is the maximum value (or actually one above the max value) of a 32 bit signed integer (that is, a Java int). If you need a higher value than that (yes, it's been known to happen), there are several high-performance SPARQL processors that implement limit and offset by a 64-bit signed integer ( = a Java long), meaning the max value is 2^63 - 1.
