SnapshotDiff CLI/API is asynchronous. The first time the API is invoked, OM
starts a background thread to calculate the SnapshotDiff, and returns "Retry"
with suggested duration for the retry operation. Once the SnapshotDiff is
computed, this API returns the diffs in multiple Pages. Within each Diff
response, OM also returns a continuation token for the client to continue from
the last batch of Diff results. This API is safe to be called multiple times
for a given snapshot source and de [...]

## Architecture
Ozone Snapshot architecture leverages the fact that data blocks once written,
remain immutable for their lifetime. These data blocks are reclaimed only when
the object key metadata that references them, is deleted from the Ozone
namespace. All of this Ozone metadata is stored on the OM nodes in the Ozone
cluster. When a user takes a snapshot of an Ozone bucket, internally the system
takes snapshot of the Ozone metadata in OM nodes. Since Ozone doesn't allow
updates to datanode blocks, in [...]
