About 0.9.2: Skip error DDL command when restart server
Hi,
In 0.9.0 - 0.9.2, if we operate an error DDL command. It will break the DDL log redo in restarting.
I fixed this in [1].
If necessary, we need to release 0.9.3 or rollback 0.9.2 ...

Hi,
I remembered we have solved a similar problem in v0.9.*. JIRA 470[1] and
JIRA 614[2]
[1] https://issues.apache.org/jira/projects/IOTDB/issues/IOTDB-470
[2] https://issues.apache.org/jira/projects/IOTDB/issues/IOTDB-614
If issue 470 only fixed "insert" statement, and issue 608 only fixed
"delete timeseries" command,
we may need to check are there other commands having such a similar issue..
Best,

Hi,
E.g.,
delete storage group root.*
We do not support use prefix path, this will be recorded in mlog and then executed with exception.
Thanks,

Hi,
Sorry for joining late.
I wonder why there is an "error" DDL in mlog.txt?
