[Satosa-dev] sharing state between satosa microservices

We did not have time in the last call to discuss this: There are use cases where we need to share state between a request and a response microservice. Now we have already 2 cases, so I suggest to define a common method to achieve this. The same approach could also be used to access the common config, e.g. if you need to know the proxy configuration (such as a backend entityid) in a microservice. A simple mechanism would be to use a module-level variable as singleton: ===================== shared_state.py state = {} ——— plugins/microservices/a.py from shared_state import state # import executes only once … state[’a’] = 'foo' ——— plugins/microservices/b.py from shared_state import state whatever(state['a‘]) ===================== I thing that for just passing request status to response microservices and passing config data around this should be good enough. There are several alternatives, like the Borg pattern, which I find harder to read. - Rainer _______________________________________________ Satosa-dev mailing list Satosa-dev at lists.sunet.se https://lists.sunet.se/listinfo/satosa-dev
