All Implemented Interfaces:

org.apache.hadoop.hdds.utils.db.CopyObject<OmSnapshotLocalData.VersionMeta>

Enclosing class:

OmSnapshotLocalData

public static class OmSnapshotLocalData.VersionMeta
extends Object
implements org.apache.hadoop.hdds.utils.db.CopyObject<OmSnapshotLocalData.VersionMeta>

Represents metadata for a specific version in a snapshot. This class maintains the version of the previous snapshot and a list of SST (Sorted String Table) files associated with the current version. It provides methods for accessing this data and supports a copy mechanism for deep cloning. Instances of this class are immutable. The list of SST files is stored as an unmodifiable list to maintain immutability.
