Enclosing class:

DataStorageSpec

public static final class DataStorageSpec.LongBytesBound
extends DataStorageSpec

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