JDBC ConfigSource Extension

Describe the extension

The idea is to have a extension that implements a ConfigSource to read properties from a JDBC Database table.

Interested in this extension, please +1 via the emoji/reaction feature of GitHub (top right).

Configuration suggestion

# Add your application.properties here, if applicable.
quarkus.jdbc-config.enabled If set to true, the application will attempt to look up the configuration from DB
quarkus.jdbc-config.table table name for configuration records, default value is "configuration"
quarkus.jdbc-config.key-column name of the column containing the key, default value is "key"
quarkus.jdbc-config.value-column name of the column containing the value, default value is "value"

Additional context

The extension can depend on agroal. It can be similar to https://github.com/microprofile-extensions/config-ext/tree/main/configsource-db, but with quarkus constrains (No JNI).

[wansors]

I’m wondering if we should group all sources in a single extension with multi modules or just keep them separate.

IMHO, I think it make sense to have them together, it would be easier to develop a new one following the same principles of the others (same style on variable names, etc). From a user point of view, it is also easier to look which ConfigSource types are available.
