Hi all, sorry to butt in.
I am little curious about why do we have to do the overwritten via
environment variables after
loading the configuration from file. Could we support to do the
substitution while loading the
"flink-conf.yaml" file?
For example, I have the following config options in my fl

Keeping the initial design as simple as possible sounds good to me.

In the end DYNAMIC_PROPERTIES behaves exactly like env.java.opts;
meaning that the existing rules set by the JVM apply.
Here's an example: export DYNAMIC_PROPERTIES='-Drest.port=1234

This would then be appended as is to the /java/ command.

@Chesnay
could you explain how underscores in user-defined properties would be

IIUC, this transformation happens in Flink and doesn't alter ENV vars, so
the user app can still parse the original configuration.

I think we have to assume that some user has a custom config option that
uses underscores.
That said, we can probably assume that no one uses other special
