Hi George, Would that be correct?
I think it is actually quite the opposite :-). It is very well explained here: https://docs.datastax.com/en/drivers/java/2.0/com/datastax/driver/core/policies/DCAwareRoundRobinPolicy.Builder.html#withUsedHostsPerRemoteDc-int- 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. ----------------------- Alain Rodriguez - al...@thelastpickle.com France The Last Pickle - Apache Cassandra Consulting http://www.thelastpickle.com 2016-05-20 17:54 GMT+02:00 George Sigletos <sigle...@textkernel.nl>: > Hello, > > Using withLocalDC="myLocalDC" and withUsedHostsPerRemoteDc>0 will > guarantee that you will connect to one of the nodes in "myLocalDC", > > but DOES NOT guarantee that your read/write request will be acknowledged > by a "myLocalDC" node.
