Joachim Durchholz commented on LBCLASSIC-187:
---------------------------------------------

PROPOSAL: Make table and column names overridable.

This allows a subclass that takes these names from configuration.
It allows alternative subclasses with hardcoded but project-speficic names.

> I'm not so much interested in table/column names, but what I would like to see is the ability to record the individual values for the placeholders in the log message.
> If you're logging to a database, there's the possibility of running report on that database. Instead of having to parse out the data from the re-combined log message (e.g. "New call made; now 4 calls active"), it would be easier to record the value of arguments directly in the database. e.g. if you've configured it so that the first argument is stored in column arg1, and the second is stored in arg2, then the log entry
> logger.info( "New call made; now {} calls active", activeCallCount );
> could appear in the database as (ignoring the other columns for this example) ...
> formatted_message: "New call made; now 4 calls active"
> arg1: "4"
> arg2: null
