We use PostgreSQL for a number of things, but we found that CDB is much faster than all competitors for Bayes. (CDB is weird in that you can't incrementally update it. You have to rewrite the entire database each time. However, this is pretty fast and the huge increase in read speed more than makes up for the rewriting.) My colleague has benchmarks at http://www.dmo.ca/blog/benchmarking-hash-databases-on-large-data/ Has anyone investigated writing a CDB backend for SpamAssassin's Bayes implementation? I'm guessing the need to rewrite the DB each time makes it a bit complex. Regards, David.
