Gee, you could really add the LMDB backend.
I use it for years (disclaimer: i wrote it, long before release
1.2.5), the per-entry overhead is smaller, the speed is
tremendous, the library is only ~7.1% of the size of libsqlite3
(here). With postfix also using LMDB exclusively (needs a patch,
AlpineLinux has it, CRUX has, too) i am all out of DBs but LMDB in
the mail system here, and that is very nice.
There is only one caveat: LMDB has no VACUUM.
So for compaction all you can do is
bogoutil -d wordlist.lmdb > /tmp/spam.db || exit 2
mv wordlist.lmdb wordlist.lmdb.save
bogoutil -l wordlist.lmdb < /tmp/spam.db || {
mv wordlist.lmdb.save wordlist.lmdb
exit 3
}
rm wordlist.lmdb.save
ie, regenerate the database, whenever you feel the need to do so.
