Configure appender from database
Hello,
I know is possible to change the configuration file dynamically, but I wonder if could be possible to configure appenders from a database, without needing to reload the full configuration file. A useful case would be to change the log level of the appender.

Right, I've dealt with configuring various things from databases in the
past, and there is no one-size-fits-all way of doing this. This is why I
mentioned a KISS set up if we were to provide anything in that dept.

That's a different beast as there is no JDBC for NoSQL...

I could think of all kinds of weird ways to do this. I could imagine an Appender table, a Logger table, a Properties table, etc. But at some point this stuff becomes somewhat free form so the schema would have to account for that.

Interesting. The simplest would be a new JDBC configuration class in Log4j
that gets a complete XML document string from DB table's column...

Yes, log4j internally would generate the new xml configuration

Will a database configuration could certainly be supported somehow, any changes to it would most likely still end up in a full reconfiguration as that is how Log4j generally handles changes to the configuration it detects.
