I'm only writing the access logs to a DB, I'm not too interested in keeping the normal logs as long as everything runs peachy.
There is actually a small comment in the JDBCAccessLogValve noting that it would be good to develop a filter on the mime type - with which one could just drop all the image request log statements, for instance.
However all the fuss about bottlenecks is all pie-in-the-sky for me, unless my website becomes hugely successful. At that point of course I'll just hire someone to develop it ;)

Hi, How about just log errors and warnings to the db? So for other types of log entry, it will still be file based; but when there is an error or a warning, in log4j, you set it up so it writes to two places. I don't notice any performance issue with this setup. But just want to confirm.
Thanks!

Howdy,
re: asynchronous DB writes - Tim pointed out the JDBCAccessLogValve. I assume you are thinking that this would quickly become a bottleneck?
Yeah, that's what I'm thinking. Writing the access log valve should be very very quick, very very scalable, or it easily becomes a bottleneck. Remember, for example, that a single page request with 9 images is 10 access log writes. 10 users asking for that page concurrently means 100 concurren access log writes, etc etc.
