public class DataOperations
extends java.lang.Object
```
Data operations that produce snapshots.
A snapshot can return the operation that created the snapshot to help other components ignore snapshots that are not needed for some tasks. For example, snapshot expiration does not need to clean up deleted files for appends, which have no deleted files.
