Generally:
a) pessimistic locking
* lock update
*run query and update state
* save the state change and unlocki
b) optimistic locking
* read a state
* run query and only update if the state has not changed in a single
transaction and commit in the same operation
I am not sure what "state" we can read here and how we can verify the state
has not changed sinve we read it.
