sa-learn --sync importance ???

[R Lists06 <li...@abbacomm.net>]

Can anyone comment on the true importance of this command and option below?

sa-learn --sync

my simple research is telling me that if you don't do this at some regular
interval, that your training isn't fully put into action when journaling
starts.

I haven't found much mention of it on the www yet I am still checking

I was tipped off by reading this doc - url and by doing a frequent  ls -axl
in the /home/spamd/.spamassassin directory on one of our servers

http://spamassassin.apache.org/full/3.1.x/doc/sa-learn.html

and by noticing that traffic on my server was generating what to my
noviceness at this is "journaling"???

am I correct?

Those in the know, Please do enlighten us all  :-)

Only when upgrading is this option *truly* important.

SA when it performs an oportunistic expiry check will sync the journal
first.

Also, unless you've enabled the "bayes_learn_to_journal" option (off by
default), the journal only contains atime updates, so this won't really
matter much.

Generally, as long as the journal is synced before an expire (and an expire
will force a sync), there's no problem.  The atime updates which is all the
journal typically tracks, are only used for expires.

Thank you Theo and Matt for the info

Do you know what the size or time threshold is?

Im sure time is a factor in there too right as maybe the size wouldn't make
it there in a reasonable timeframe?

Puts the journal information into the DB.

I didn't quite parse that.  But "man sa-learn", it has many an informational
statement about how it all works.

In short, by default, it stores token timestamp updates.  Whenever the journal
goes over a certain size, SA will automatically sync it for you.
