Nic Townsend updated FLINK-39441:
---------------------------------
Description:
https://nightlies.apache.org/flink/flink-docs-release-2.2/docs/dev/table/config/
says:
{quote}Note: All of the following configuration options can also be set
globally in Flink configuration file and can be later on overridden in the
application, through EnvironmentSettings, before instantiating the
TableEnvironment, or through the TableConfig of the TableEnvironment.{quote}
However, when I set {{table.exec.source.idle-timeout}} on a {{FlinkDeployment}}
- it makes its way to the configuration but it doesn't take effect.

I have use to use {[SET 'table.exec.source.idle-timeout' = '10s'}} inside my
executed SQL or use {{scan.watermark.idle-timeout}}.
My usecase is that I have a containerised SQL runner application - it just runs
the SQL that I supply. As such, I don't want to hard code values when creating
{{TableEnvironment}} and I want to set it on the individual {{FlinkDeployment}}
instead
