| If you have data that is best handled as a blob, such as structs that do not contain pointers, use the serializable type `CacheableBytes` . `CacheableBytes` is a blob class that implements the serialization for you. |
| |
| `CacheableBytes` also provides direct access to the blob data. Because it is not derived from the `CacheableKey` interface, `CacheableBytes` enables you to modify data in place and then put it into the region again to distribute the change. |
