            Is there a Pub Sub service where publishers only send messages to a given topic if there are subscribers?
            Asked 2020-Jul-14 at 09:35

            I'm looking for a scalable pub sub cluster where it's possible that publishers only send messages for a given topic to socketcluster if there are subscribers?

            The reason being is that all of my publishers process millions of messages for many topics which for long periods won't have subscribers. So it's a huge waste computationally and price wise to send everything to the pub sub cluster.



            Answered 2020-Jul-14 at 09:35

            PubSub is designed to decouple the subscribers and the publisher. So, your request is an anti-pattern of PubSub.

            Anyway, if you publish a message into PubSub and there isn't subscription (I said "subsciprions" not "subscriber"), the message is dropped. Your publishers can still check if a subscription exists on a topic before processing the messages. Subscribers check isn't possible.

            If there is one (or many) subscription, the message is send to it (if several subscription, the message is duplicated). The message are kept up to 7 days in the subscription, but you can reduce this duration according with your use case. by the way, when a subscriber will listen the subscription, it will be able to only receives and processes the relevant message, not the too old ones.



            I cannot access my variable inside socket.on of socketcluster

            this context, almost certainly. I'm not entirely certain what this context will a function called inside socket.on get, but arrow functions use the lexical this, so that would be one solution.



            Express server blocked with Sockets
            Asked 2019-Dec-07 at 14:02

            I have a problem, I am mounting an express server with Sockets (module socketcluster-server) but when I am sending http requests the express is blocked after about 20 requests, causing the Sockets (client) to notify that they have run out Connection.

            Has someone happened to you? Any ideas that can help me solve this problem?

            Thank you

            Is a feature that kubernetes is sharing all services as env variables?
            Asked 2019-Jan-23 at 23:16

            I was setting up a laravel and socketcluster install on kubernetes and when try to add redis to laravel got an error about an env variable that i doesn't have defined, so when i print all the env variables in any container i get all the variables from others services like this:



            Answered 2019-Jan-23 at 23:16

            It's a feature. For every Service in the same namespace, you get OTHERSVC_SERVICE_HOST and OTHERSVC_SERVICE_PORT environment variables, plus some others that come from the legacy Docker links feature. I don't know of any way to turn these off.

            Actually using these is problematic in practice, because it depends on the consuming pod starting after the producing service is up, which is hard to guarantee; DNS lookups othersvc.default.svc.cluster.local may not resolve at runtime but won't have a missing environment variable. Conversely, if you might configure your pod with an environment variable named something like MICRO_SERVICE_HOST or DATABASE_PORT, those names are liable to be "stepped on" by the generated environment variables.

            Asked 2018-Sep-04 at 04:19

            I am trying to create a debug build of my app in react-native. It worked previously and the problem started after I used react-native-tools extension package for VSCode text editor and attached its debugger for debugging. The error doesn't occur when I create a release build. I have removed the extension, removed my project node_modules folder and reinstalled.

            The error is as follows:

            The error was emerging from the react-native-firebase package.

            Updating the react-native-firebase package to the latest version resolved my problem.
