Hi John, > 1) I am currently testing a setup where a broker would bridge to 1 or more > brokers so that similar messages are funneled into one place.

There is no inherent limit, but you have to be careful how the topics are mapped between brokers so that you avoid loops. > 2) Is it possible for mosquitto to use all of the available RAM on a > machine, or is it capped at a certain limit? There is no global resource limit at the moment. > 3) How long does it take to save the in-memory database to disk If you have > a large amount of subscriptions (100k+) and messages? You'd have to check that on your particular system. > 4) If you had a broker running on a server that crashed and you had a backup > of the database file, would there be any problems copying it over to a new > server and starting a new broker with the database file? The only time there would be a problem is if the two machines didn't have the same endianness.
