My employer (Invenia) runs Memento.jl (a logging package) in production, hooking in variously to SumoLogic and AWS Cloudwatch and from their into PagerDuty. I would say it is production grade logging. and it is integrated enough with standard lib logging that stuff logged using that also ends up at the right place. I don't think it would actually be that hard to get the stdlib logging to work directly with that kind of system either. (Probably if we were starding today we might have built ontop of the stdlib logging, but Memento is a bit older than that, and a bit different in philosophy) THere are a bunch of database drivers. We use LibPQ.jl in production. I hear good things also about OCDB.jl, and SQLite.jl also. and anything to do with data is really nice because of how interoperable all the data-frames like packges are. Everything just works together as long as the minimal API described by Tables.jl is implemented. (and everything implements that)
