Hi – I have 2 data centres (DC1 and DC2) and I have local_quorum set as the CL for reads. Say there is a RF factor = 2. (so 2 copies each in DC).

 

If both nodes which own the data in DC1 are down and I do a read with CL as “local_quorum” , will I get an error back to the application ? or will Cassandra do automatic routing to the other DC ?

 

Thanks,
