> Operator currently cannot handle tables where old data is periodically
> removed, because the poll logic assumes a fixed start offset. Instead, it
> should support offset rebase with a trailing lower bound key.
> Such use of the WHERE clause will also avoid repeated full index scanning and
> be especially efficient when the source is partitioned on the key column.
