Review Comment:
> Do we have other kind of offset other than `lsn` in Oracle? If `lsn` is
the only kind of offset, we can upgrade this into a ConfigOption.
There may be others, but I understand this is a common property of
incremental snapshots? For example, other data sources may also require
starting from a specified offset.
