   @DenizPiri Thanks for your feedback and give the credit to @PragmaTwice 
great work.
   
   > If we were to use WATCH/UNWATCH support more widely in our other projects 
too, assuming that 99.9% of the time transactions will execute without any 
conflicts. Should we expect degraded performance, possibly because of a lock 
contention?
   
   Yes, it may have a performance issue since the MULTI-EXEC is an exclusive 
operation even though most of the commands are no conflicts. I'm also seeking a 
way to improve this situation, but you can have a simple benchmark before using 
it.
