Having an issue with Cassandra & multiple data centers

We are seeing an interesting behavior within our Cassandra connections. It appears as though Datacenter B's API gateways are preferring Datacenter A's Cassandra cluster.

 

Our contact point configurations are as follows:
Datacenter A Contact points:

  1. Datacenter A Cassandra
  2. Datacenter B Cassandra

Datacenter B Contact points:

  1. Datacenter B Cassandra
  2. Datacenter A Cassandra
       

We are unsure why the Datacenter B gateways are preferring Datacenter A Cassandra nodes. Any insight would be appreciated.

 

 

Are the contact points ordering not respected? How are the contact points decided?
