-------------------------------------
Summary: DataGen sequence generator requires the definition of
start/end values
Key: FLINK-31084
URL: https://issues.apache.org/jira/browse/FLINK-31084
Project: Flink
Issue Type: Improvement
Components: Connectors / Common
Affects Versions: 1.16.1, 1.15.3, 1.17.0
Reporter: Matthias Pohl
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.
