The only thing I’ve noticed is that missing?
doesn’t complain when you ask for a never-transacted attribute (i.e. (missing? $ ?e :random-made-up-or-misspelled-kw)
)
Can you configure the path to ion-config.edn
? I have slightly different configurations per environment.
is it possible that two jvm processes share the same valcache (directory) for a short period of time? our deployment first starts a new version before it stops the old one
Yes, I believe valcache directory can be shared, but it has not been tested. Not to put you out on a limb, but if you notice any issues could you send them to me in support? And I encourage you to test in non-production first.
