> After we log our events to spark's event logger, they become raw JSON data, why do we need `ElementTrackingStore` here? The `ElementTrackingStore` is provided in the `org.apache.spark.sql.hive.thriftserver.ui.HiveThriftServer2HistoryServerPlugin#createListeners` method to initialize the SparkListener. Previously, EngineEvents were stored in `org.apache.kyuubi.engine.spark.events.EngineEventsStore`, after using `ElementTrackingStore`, it will be stored in `org.apache.spark.util.kvstore.InMemoryStore`. -- This is an automated message from the Apache Git Service.
