This should be carefully studied.
I wanted to ask about this after I've published the revised scale-out design wiki, but I'm taking too long, so could you share your study results? I think we need to make it clear about the patent before discussing the code. After we hear your opinion, we also have to check to see if Clock-SI is patented or avoid it by modifying part of the algorithm. Just in case we cannot use it, we have to proceed with thinking about alternatives. Regards Takayuki Tsunakawa
