public interface SnapshotTrigger
It is up to the Trigger implementation to decide when, how and where a snapshot is triggered.
SnapshotTrigger implementations do not need to be thread-safe.
It is highly recommended to make trigger instances Serializable
. The trigger instance is attached to the
aggregate instance which it monitors, causing it to be cached and potentially serialized alongside it.
