kangkaisen opened a new issue #2735: Consistent check will block transaction finish URL: https://github.com/apache/incubator-doris/issues/2735 **Describe the bug** ``` 2020-01-11 01:28:02,778 INFO 3999 [GlobalTransactionMgr.beginTransaction():165] begin transaction: txn id 818881459 with label insert_917325ae-a7c1-4993-a43f-2ded1f8236c0 from coordinator FE: 10.180.16.213 2020-01-11 01:28:02,778 DEBUG 33 [ConsistencyChecker.chooseTablet():334] tablet[188045291]'s version[48-3353073017075980381] has been checked. ignore 2020-01-11 01:28:02,779 DEBUG 33 [ConsistencyChecker.chooseTablet():334] tablet[188045279]'s version[48-3353073017075980381] has been checked. ignore 2020-01-11 01:28:03,570 INFO 36 [GlobalTransactionMgr.finishTransaction():605] transactionId 818881342 partition commitInfo version 11591partition visible version 11590 2020-01-11 01:28:03,571 INFO 36 [GlobalTransactionMgr.finishTransaction():605] transactionId 818881342 partition commitInfo version 270partition visible version 269 ```  The `palo.fe.load.total.value` is the number of running transaction. From the log and picture, **we could know the ConsistencyChecker block the transaction finish, because they both need to hold the DB lock.**
