Subject Re: Consistency level ONE and using withLocalDC
Date Wed, 08 Jun 2016 17:10:22 GMT
Hi George,

Would that be correct?

I think it is actually quite the opposite :-).

It is very well explained here:

Connection is opened to the X nodes in the remote DC. But it will only be
used to indeed do a local operation as a fallback if the operation is not
using a LOCAL_* consistency level.

Sorry I have been so long answering you.
