> * If we don't set `spark.history.store.path`, it will use memory to store app info and it's not belong to LevelDB metrics, right? Yes, correct. In this case, it will only use the in memory key value store. > * Only when support hybrid store disk backend, then we have in-memory LevelDBs, right? I don't quite get the question here. When hybrid mode is enabled, the in-memory store used during parsing is called [InMemoryStore](https://github.com/apache/spark/blob/master/common/kvstore/src/main/java/org/apache/spark/util/kvstore/InMemoryStore.java#L45), not the actual LevelDB. -- This is an automated message from the Apache Git Service.
