StorageTable
interface StorageTable
A storage unit that holds a collection of items. An item is a ByteString indexed by a unique key.
BaseStorageTable has two optional features: partitioning and expiration.
When the table is partitioned, each item is actually indexed by a key pair (partitionId, key). Keys are unique only within a particular partition.
When item expiration is enabled, each item can be given optional expiration time. An item is (conceptually) silently and automatically deleted once clock time goes past expiration time (in other words, an item still exists at exactly the expiration time).
