2015-12-27 22:31:32 -0700 edited answer RESTCONF Troubleshooting

when u add flow that will 1st added into config data store and then it will added into operational data store.so it is not necessory that every flow which is present on config data store should present on operational data store.if it does not getting added in operational data store: there may be following issues 1.may be format of flow body is wrong 2.dl_type is always necessory if u are specifing ipv4 source and destination in match 3.if u are using ovs switches check the version of ovs. some times ovs with 2.0.2 supports some flow format but above version will not 4.if u are using openvswitch .u can check logs with/var/log/openvswitch

For Refrence U can go through following application: https://github.com/ashvini/pythonapp

2015-09-29 21:02:08 -0700 answered a question What happens when a disconnected switch reconnects to the controller?

Hi , Actully persistent characteristics of config data store is depend on release of opendaylight. if you are using lithium/stable then only config data store is persistence otherwise i think previous release of opendaylight not offering persistence feature for config data store.
