sjwiesman opened a new pull request #13010:
URL: https://github.com/apache/flink/pull/13010
## What is the purpose of the change
Updates the DataGen source to support most types. This enables using DataGen
in conjunction with Flink's LIKE clause as it currently does not support
overwriting physical columns with computed columns.
## Brief change log
I refactored the table factory and added support for all types except RAW
and STRUCTURED. See commit messages for a full list of changes. I also added
support for creating bounded tables which is useful when prototyping a query.
## Verifying this change
