You can try turn off insert delayed,but batch insert will be affected。 vi my.cnf tianmu_insert_delayed=off

[zhenglin-charlie-li]

Ok yes, setting tianmu_insert_delayed=0 solved this issue.

By the way, I am developing SQLancer to let it support StoneDB. Do you developers consider this issue as a bug or not?

If it is not a bug, we will do the above operation to avoid this probelm.

[haitaoguan]

We will fix these issues,and you can turn off the insert delay during testing.
