------------------------------
> JDBCPollInputOperator support for offset rebase
> -----------------------------------------------
>
> Key: APEXMALHAR-2514
> URL: https://issues.apache.org/jira/browse/APEXMALHAR-2514
> Project: Apache Apex Malhar
> Issue Type: Improvement
> Reporter: Thomas Weise
> Assignee: Thomas Weise
> Fix For: 3.8.0
>
>
> 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.
