> Key: FLINK-18654
> URL: https://issues.apache.org/jira/browse/FLINK-18654
> Project: Flink
> Issue Type: New Feature
> Components: Connectors / JDBC, Documentation
> Affects Versions: 1.11.0
> Reporter: Jark Wu
> Priority: Major
> Fix For: 1.12.0, 1.11.3
>
>
> In
> https://ci.apache.org/projects/flink/flink-docs-master/dev/table/connectors/jdbc.html#partitioned-scan
> > Notice that scan.partition.lower-bound and scan.partition.upper-bound are
> > just used to decide the partition stride, not for filtering the rows in
> > table. So all rows in the table will be partitioned and returned.
> The "not for filtering the rows in table" is not correct, actually, if
> partition bounds is defined, it only scans rows in the bound range.
> Besides, maybe it would be better to add some practice suggestion, for
> example,
> "If it is a batch job, I think it also doable to get the max and min value
> first before submitting the flink job."
