Hi all, Seems the thread model of tajo storage layer is quite complex. Each call of StorageManagerFactory.getStorageManager(TajoConf) creates one instance of StorageManagerV2, which creates a scan scheduler thread and several disk file scan schedulers threads. Why those threads are needed? What's their function? How do those threads work with file scanners?
