Hi, Dear all, After following the documents listed in the MD-SAL wiki and source code, I still have two problems which confusing me two weeks.
1.When will the Config Tree be persisted into the hard-disk? In my understanding, In-Memory DataStore stores two trees: Config tree and Operational tree. The Config Tree will be persisted into the hard-disk after serialization as a journal using AKKA toolkit. It will happen once the data changed, but I've no idea when does it happen? For example, a data store writing operation will write the given data into the in-memory DataStore, but I don't know whether this transaction return immediately when successfully write into the in-memory DataStore or return till merge into the hard-disk. 2.What's the difference In-Memory DataStore and Distributed DataStore? It looks like Distributed DataStore implement DOMStore interface so that replace In-Memory DataStore, as a result, it uses ShardTransaction which is an actor to serialize data and then write into hard-disk. Is my understanding correct? Many thanks for any advice. Best Regards, Vinllen
