Enhancement: TOML Config Source for MicroProfile Config /FISH-9198 #6822

Open poikilotherm opened 1 month ago

poikilotherm commented 1 month ago

Brief Summary

I would like to be able to use a TOML file as a source for configuration values. This is a standard feature for SmallRye and should be included in Payara, too.

Expected Outcome

Just configure a source and read away that TOML file!

Current Outcome

I'm stuck with adding such a config source to the application, which does not allow me to provide values for early init stuff like ${MPCONFIG=...:...} variable replacements.

Alternatives

Implement a fake JDBC driver to read TOML files.

Been there, done that: gdcc/jdbc-conffile-driver Works, but is hacky. Also: a config source that reads a local file can be updated on change and doesn't need 60 secs default caching! But this will require more control over what's going on, which is just not possible with the JDBC workaround.

Context

As with the DirConfigSource (#5006 / #5007), I would be willing and able to create a pull request and donate the necessary code. If accepted, we should talk about the location for this config source (fish.payara.microprofile.config.extensions vs fish.payara.nucleus.microprofile.config.source) and potentially about using a different caching strategy for it.
