/**
 * A shard is a single "piece" of information, such as a snippet of text, login
 * credentials, an image, or a private key. All shards within a cluster should
 * have unique names.
 * <p>
 *     Due to the need to deserialize shards from byte arrays, it is required
 *     that this parent class holds a type discriminator value, which is used to
 *     decide which shard type to deserialize.
