---------------------------------
Summary: Datagen connector does not list its available options
with placeholders
Key: FLINK-22475
URL: https://issues.apache.org/jira/browse/FLINK-22475
Project: Flink
Issue Type: Improvement
Components: Table SQL / Planner
Affects Versions: 1.12.2, 1.13.0
Reporter: Ingo Bürk
The Datagen connector provides optional options like "field.#.max" which
contain placeholders as the option is to be set per-field. However, its factory
does not list these placeholder options at all.
In order to generate connector documentation from code, the factory should list
these placeholder options.
Additionally, we should "standardize" the usage of '#' as a placeholder,
document it on the Factory interface and possibly even extend the validation
helper to 1) ignore required properties containing a '#' and 2) reject provided
options containing a '#' in their key.
