Yes, that is more valuable, and as mentioned by Mihail, we are already
discussing the same. However, that has its own challenges, like it
needs some form of manual management by the user to clean up the
conflict_history table. Also, one can say that because table insert is
a heavy operation and more prone to failures, it is better to LOG it.
Yes, the user would require some form of script to extract the
information from the LOG, so both methods have their pros and cons. I
think we will need a configurable knob to let the user decide which
way they prefer to log the conflict information.
