Re: [hono-dev] Multi-Tenancy configuration in Qpid dispatch router

Hi Bala,

we are currently using Dispatch Router 0.7.0 which does not support the "multiTenant" property:

https://github.com/apache/qpid-dispatch/blob/0.7.x/python/qpid_dispatch/management/qdrouter.json

I have no idea what it is supposed to do and, consequently, do not know whether it would help to achieve what we need.

But thanks for the hint :-)

We are also currently not defining tenants per se but we only define groups for authorizing access to addresses (as you already found out).

Virtual hosts wouldn't help us FMPOV as the tenant information is encoded in the address of the messages. We use this approach so that receivers from arbitrary tenants can receive messages sent to arbitrary addresses. I do not think that we could achieve this with using a virtual host per tenant because a receiver could then only receive messages that have been sent to the same virtual host that the receiver has connected to.

Mit freundlichen Grüßen / Best regards

Subject: [hono-dev] Multi-Tenancy configuration in Qpid dispatch router

 

 

Hi There,

 

I have a question regarding the multi-tenant configuration in Hono’s Qpid dispatch router. Currently tenants like DEFAULT_TENANT, anotherTenant are configured as Groups within the broker’s virtual host „hono“.

 

As far as I could see there are also other ways to configure like

1. A separate virtual host for each tenant

2. The Qpid listener also a multi-tenant boolean flag that can be configured in qdrouterd.json - https://github.com/apache/qpid-dispatch/blob/master/python/qpid_dispatch/management/qdrouter.json#L665 (not sure how the tenants can be configured after that but still interesting to find out)

 

There must a reason why the multi-tenancy was done differently in Qpid dispatch router than the obvious choice like separate virtual hosts. Can any one point me in the right direction to find it?

 

Regards,

Bala
