Well, my previous remark applies equally well to this ticket so let me just

I'm not a fan of blanket statements like that. There is a high cost to
SERIAL
consistency in multi-DC setups, but if you *need* global linearizability,
then
you have no choice and the latency may be acceptable for your use case. Take

Hi DuyHai,
Thank you for the comments.
Yes, that's exactly what I mean.
(Your comment is very helpful to support my opinion.)
As you said, SERIAL with multi-DCs incurs latency increase,
but it's a trade-off between latency and high availability bacause one
DC can be down from a disaster.
I don't

The reason you don't want to use SERIAL in multi-DC clusters is the
prohibitive cost of lightweight transaction (in term of latency),
especially if your data centers are separated by continents. A ping from
London to New York takes 52ms just by speed of light in optic cable. Since

Hi,
I have been using lightweight transactions for several months now and
wondering what is the benefit of having LOCAL_SERIAL serial consistency level.
With SERIAL, it achieves global linearlizability,
but with LOCAL_SERIAL, it only achieves DC-local linearlizability,
which is missing point of l
