Hi,
as I am trying to simplify current entry wrapping and distribution code,
I often find that listeners can get wrong previous value in the event,
and it sometimes forces the command to load the value even if it is not
needed for the command.
I am wondering if we should change the previous value in events to
Optional - we can usually at least detect that we cannot provide a
reliable value (e.g. after retry due to topology change, or because the
command did not bothered to load the previous value from cache loader)
and return empty Optional.
WDYT?
