Hi, contractually there is only limitation fo CE production use and that is possible data sources. Only Opensource data sources can be used for production, so out of supported ines it is postgress and drill.
No other functional limitations. Of course, performance wise you have to count with fact that single docker image with all the services inside will perform worse (response time, large datasets handling etc.) than k8 deployments. But this depends on usecase and you need to test whether it fullfill your needs as based on you data size etc.
