VersionOffsetSnapshotStrategy
class VersionOffsetSnapshotStrategy(versionOffset: Int = DEFAULT_VERSION_OFFSET, snapshotRepository: SnapshotRepository) : SnapshotStrategy
Snapshot strategy that creates snapshots based on version offset. A snapshot is created when the current aggregate version exceeds the last snapshot version by the specified offset. This helps balance between snapshot frequency and storage efficiency.
Parameters
versionOffset
The minimum version difference required to trigger a snapshot (default: DEFAULT_VERSION_OFFSET).
snapshotRepository
The repository to save snapshots to.
