The biggest hurdle was realizing that dispatch.yaml, queue.yaml, cron.yaml, index.yaml all update separately from the app(s)/modules themselves. (update_dispatch, update_queue, etc.)
Other than that, it is really easy and you should totally do it. If your url namespace is well structured, you can use dispatch.yaml to move traffic to different modules very, very easily. j On Friday, 10 October 2014 17:33:09 UTC-6, Kaan Soral wrote: > > I've been interested in Modules, mainly to: > 1) Seperate the logs / components of the app, to ease the debugging and > monitoring > 2) Hope to increase the performance, leave the frontend instances to > user-facing requests only (?) > > The documentation is very adequate, however, as all services, you have to > dive into it to actually learn it > > What I learned: > 1) You have to use a manual appcfg command, manually cd the directory, > appcfg update app.yaml module.yaml's > (Which is something everyone should do anyway, imo, I only use the > gui/launcher for deployment, I will probably not do that anymore) > 2) Each module seems to be like a separate app, that shares the appengine > services like datastore etc. (Great!) > 3) Each module gets uploaded separately (the command does this), > multiplying the deployment time/risk > (It's kind of obvious, as module's are separate components, however the > risks are unknown) > (Does the rollback command work the same way? - for example this is one > risk, unknown) > 4) The UI/AppEngine Console improves with module tabs at each tab like > Dashboard/Instances/Logs/Versions (Great!) > 5) Each module .yaml should include everything, similar to app.yaml, like > libraries etc > 6) I'm guessing the costs will increase a bit, however, it might also > decrease the costs of some high traffic apps as it will allow throttling at > the backend level > > I have some questions to those who are experienced with Modules: > 1) Are there any side-effects, not obvious thing that are major road > blocks?
