   By the way, too much DatabaseTransactionMgr will cause some more serious accident.For example, if DatabaseTransactionMgr costs too much memory, checkpoint image will not work because it will check java heap memory in order to create image in memory, so when FE down cause by OOM, it will replay too much EditLog, in the worst case, it will replay more than one hour, It means that data load is not available in the meantime.
