------------------------------------------
[~agoncharuk] Hi!
In current master branch I came across odd behavior, consider the following
scenario:
T1:
Start optimistic READ_COMMITTED tx, run cache.invoke(); // This cache invoke
fetches the key from primary node and stores into tx entry. This Invoke doesn't
change the value.
T2:
run cache.put();// which overwrites the original value;
T1:
run cache.read();// Here and futher old value will be returned, because of
invoke() called above.
commit();
In this scenario we have no Non-Repeatable Reads, which seems incorrect for
READ_COMMITTED isolation mode.
Do you agree ? If yes, I will file another new ticket, fixing it.
