> When execute an InsertPlan, we first check whether the timeseries exists or
> not. Then we write the InsertPlan to WAL and insert it to memtable. However,
> if the data type mismatches the registered schema, WAL will still be written
> but inserting to memtable will fail.
>
> When restart IoTDB, the WAL cannot be replayed due to NumberFormatException
> and IoTDB will fail to restart.
