I'm sorry to be late to respond. Thank you for the update.
As discussed at the HighGo meeting, what do you think we should do about this patch set, now that we agreed that
Clock-SIis covered by Microsoft's patent? I'd appreciate it if you could share some idea to change part of the
algorithmand circumvent the patent.
Otherwise, why don't we discuss alternatives, such as the Commitment Ordering?
I have a hunch that YugabyteDB's method seems promising, which I wrote in the following wiki. Of course, we should
makeefforts to see if it's patented before diving deeper into the design or implementation.
