Dan Berindei commented on ISPN-4018:
------------------------------------
To me it makes sense to do the write skew check for all the values that were read by the
transaction, regardless if they are written to or not. Of course, if the conditional
operation was the only write in the transaction, then the transaction is effectively
read-only and shouldn't be replicated at all.
Write skew should not be check if conditional operations does not
change the value
----------------------------------------------------------------------------------
Key: ISPN-4018
URL: https://issues.jboss.org/browse/ISPN-4018
Project: Infinispan
Issue Type: Bug
Components: Core, Transactions
Affects Versions: 6.0.1.Final
Reporter: Pedro Ruivo
Assignee: Pedro Ruivo
Fix For: 7.0.0.Alpha1, 7.0.0.Final
Currently, if a conditional operation does no perform the update, we still perform the
check. however, the write never happened. It simple makes no sense.
However, if a write succeeds after, the write skew check must be performed for the key.
