Enclosing class:

DataStorageSpec

public static final class DataStorageSpec.IntMebibytesBound
extends DataStorageSpec

Represents a data storage quantity used for Cassandra configuration. The bound is [0, Integer.MAX_VALUE) in mebibytes. If the user sets a different unit - we still validate that converted to mebibytes the quantity will not exceed that upper bound. (CASSANDRA-17571)
