Mass creation of virtual hosts

[William Edwards]

Hello,

I have about 5.000 'mini' users. I expect this number to grow. These users should not be able to access anything belonging to other users. I can think of two approaches:

- Use the user's name or ID as message topic on a topic exchange, and create a user permission for only that topic

- Create a virtual host per user, with their own exchanges etc.

I prefer the second option, because the more isolation, the better. However, I am wondering if creating that many virtual hosts is supported. I cannot think of any reason why it wouldn't. Each user will receive 2 messages a day at most, so each user's usage is very minimal, but of course there still has to be an exchange in memory for each user.

Questions:

- Can I expect any problems creating that many virtual hosts?

- What kind of memory usage can I expect? Each virtual host will have about 3 exchanges, so 5.000 * 3 = 15.000 exchanges in memory.

Maybe someone can share some insights.
