Do you have any information about how and when SA3 expires information from the bayesian database? I'd like to "preinstall" a pretrained database for each user und hope that the database is not emptied on instant if I add a user in three month with the database from today.
I don't know for sure, but I imagine the expiry is similar to what's used in SA 2.5x and 2.6x. It may have some differences in the exact details, but from a high-level perspective it should be similar.
For reference, the method is:
when the number of tokens in the database exceedes bayes_expiry_max_db_size expire the least recently used tokens until there are only 75% of bayes_expiry_max_db_size tokens left. Never expire to contain less than 100,000 tokens regardless of what the max_db_size is.
Thus you shouldn't run into problems. SA will never completely empty the bayes DB via expiry.
