Creating vhosts dynamically in Java broker
Hi,
Can I create virtual hosts dynamically in the Java broker?.
ApplicationRegistry.createVirtualHost would do?.
Thanks,
Danushka

Plus object distinction.
For an example, users in different tenants should be able to create a
destination with the same name but they should have distinct names in the
broker. So tenant T1 and T2 should be able to create queue Q so that they
have distinct names in the broker. (say T1-Q and T2-Q)

Rajith, will this help the scenario that I have mentioned above?. If so then
I am through :-). Thank you!.

Is that correct ?
If thats the case, one workaround that I can think of is to just have one
virtualhost and use namespaces for partitioning your exchanges and queues
and set the ACL's based on that. That is each tenant has a unique
id/prefix/name and all exchanges and queues setup for them can use this
prefix.
I really don't think that not being able to create virtual hosts dynamically
is a blocker.
I also don't think virtual hosts is particularly a useful feature either. I
don't think it really adds any value. YMMV.
The C++ broker does not even support it.

Rajith

Hi Robbie,
How much work do you think it is?.

Re: Creating vhosts dynamically in Java broker

I see. Well as I say, it isnt currently supported but wouldnt be hard to
actually create them dynamically. The issue is that the broker is not set up
to persist or recover such information and so the only path for doing so is
currently the configuration file (which leads into a larger overall issue
with the way the broker stores its configuration in multiple places,
something which already needs a fair bit of work).

Hi Robbie,
I need to use Qpid in a SaaS implementation so that need to have virtualhost
per tenant. The tenants are created dynamically. Hence I need to create
vhosts dynamically.
Hope you get my point.

Danushka

Hi Danushka,
I dont think the situation has changed any since you asked this previously;
it isnt currently possible although it shouldnt involve much to make it so.
Andrew and I both enquired at the time as to what the end goal for doing
this would really be?
