We're working on a project , and we want to use some toggling feature tool like ff4j or togglz but we have a real constraints about performances, i mean we really need a tool with the less time of execution , i've checked a little bit ff4j and togglz but i don't know what is best for this solution, or may be if you know some other tools.
Context of project: its a netflix microservices architecture, so we have eureka,ribbon,zuul and microservices.
otherwise , if you have another solution , may be develop a sidecar please give me some ideas.
thank you in advance :)
Disclaimer : I created FF4j, as such I won't give you answer relative to performance comparison. I will provide architecture design principles.
Microservices means distributed architecture so you will have to store the state of your features in a common persistence storage (DB).
The cost of feature toggle framework won't be time to evaluate the feature state predicate (it is a simple condition) it will be the time to access the data from the persistence storage.
FF4j provides support for both REDIS and CONSUL:
If you have to store your features in a slower DB such as SQL-Like then you might consider to use caching. FF4j provides some
cacheProxy
to handle such use cases.Other Considerations :
