FWIW, we hit the routes limit on DEA as well. But that limit was much more
than 4K. Fortunately, our service could use the wildcard in the routes and
so we started using that. So I dont believe its specific to Diego.

While we are looking into a change on our side, can someone share with us
the reason of the limit introduced to Diego on the maximum size of an
application's routes? It was not there with DEA. I like to see that a
change is made in Diego to to make this parameter configurable.

Thanks,

Wouldn't it be better to use a single URL and implement the auth and
separation in the app via token or something rather than by host URL? Or if
you need to do that maybe have a micro proxy app per customer which has the
main app registered as a service? It seems a lot of overhead to have that
many routes per app

Daniel,

Our apps support multi-tenancy and our customers are enterprise
customers. For each subscription, there is unique ur which is mapped to the
same app. Therefore for 500 subscriptions there are 500 routes. This new
limitation introduced in Diego would break our production.

Can someone share the reason for introducing the limitation?

Thanks,

Jason

Hi Maggie,

That's an unusual number of routes for a single app. Could you explain
the use case please, so we can attempt to think of other solutions to the
problem?

Hi,



We have one application with over 200 routes and one application with
over 400 routes. And we expect more routes will be created with more
subscriptions coming.



But those applications can’t run in Diego container due to the maximum
size limitation of 4KB as mentioned in https://discuss.pivotal.io/hc/
en-us/articles/230433388-Migrating-Applications-from-DEAs-to-Diego



Diego imposes a 4KB limit on the maximum size of an application's
routes. While this doesn't translate to a specific number of routes, as
it would depend on how many characters are in each routes, we are
estimating that gives you space for 40 to 50 medium sized (50 character)
routes. If you have too many routes bound to your application, you'll see
the error *Runner error: desire app failed: 503.* In some cases you
can work around this by using a wildcard route (i.e. *.my-domain.com)
instead of mapping individual routes. When that is not possible, the only
other option is to run multiple applications mapping 40 to 50 routes to
each application.



Apparently wildcard is not an option and we don’t want to split
applications just because we can’t add more routes. Is there any other
solution? And would anyone help to explain why this limitation is
necessary? I don’t remember same issue existed in DEA.



Thanks,

Maggie
