Maximum size limitation of Diego apps' routes

Meng, Xiangyi <Xiangyi.Meng@...>


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

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. * 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.
