---------------------------------------

yes, that's what I had in mind.

> DataGen sequence generator requires the definition of start/end values

>                 URL: https://issues.apache.org/jira/browse/FLINK-31084
>             Project: Flink
>          Issue Type: Improvement
>          Components: Connectors / Common
>    Affects Versions: 1.17.0, 1.15.3, 1.16.1
>            Reporter: Matthias Pohl
>            Priority: Major
>              Labels: starter

> The [DataGen connector's 
> parameters|https://nightlies.apache.org/flink/flink-docs-release-1.16/docs/connectors/table/datagen/#connector-options]
>  are not precisely documented: The start/end parameters are labeled as 
> required for the sequence generator even though they are (see 
> [SequenceGeneratorVisitor:85ff|https://github.com/apache/flink/blob/ef9ce854a3169014001f39e0d5908c703453f2b8/flink-table/flink-table-api-java-bridge/src/main/java/org/apache/flink/connector/datagen/table/SequenceGeneratorVisitor.java#L85]).
> But instead of updating the documentation, we should just come up with 
> reasonable default values. As a user, I would expect the positive integer 
> values to be returned starting from 0 if I don't specify anything here.
