EACH_QUORUM for one DC

[Chong Zhang <ch...@gmail.com>]

Hi,

If there is only one DC, can we still use EACH_QUORUM for write? We only
have one DC now, but will build another one in future and like to use
EACH_QUORUM when there are two. But like to know if it's good to use
EACH_QUORUM with the current 1 DC.

And if there are two DCs but in some cases one whole DC cluster is down,
does that mean all the writes are going to fail?

Thanks,
Chong
