It's a setup with a dedicate-write database and a dedicated-read database. My assumption (which seems to be going well) is that the Bayesian database can be a little out of date (hours or even a day) and still be very effective at decision-making. So I dump the writeable database to the read-only database at regular intervales and the SQL in SpamAssassin's BayesStore module was all modified to do the write queries in one DB and the read queries in the other. I documented it with more detail on my site just a few minutes ago, with graphs to demonstrate the improved performance: http://www.jenandneil.com/node/59 If anyone sees any places I should expand on that, by all means let me know. I'm pretty proud of the results. After it runs for a bit longer, I was going to send it along to Apache/SpamAssassin as a feature request, suggestion. -N _______________________________________________ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
