方法详细资料

reportStorageGroupStatus

public boolean reportStorageGroupStatus(StorageGroupInfo storageGroupInfo,
                                        TsFileProcessor tsFileProcessor)
                                 throws WriteProcessRejectException

Report current mem cost of storage group to system. Called when the memory of storage group newly accumulates to IoTDBConfig.getStorageGroupSizeReportThreshold()

参数:

storageGroupInfo - storage group

抛出:

WriteProcessRejectException
