Use Service Records

[Malte]

Hi there,

I is it possible to use service records as contact point for the java driver in order to connect to a cluster? In the documentation I wasn't able to find anything in this regards.

All the best

Hi Malte,

To my knowledge this is not currently supported, but does sound like it a good option.   There is a feature request, JAVA-1082, for allowing specification of an API that provides contact points that could be used for implementing this.   The driver will resolve multiple IPs from A/AAAA records though (JAVA-925) if you wanted a way to represent all contact points/nodes in a DNS record.

Thanks,

Andy

Hi Malte,

Have you tried passing the DNS name? I haven't looked into the Cassandra driver code however if you pass the DNS name to INetSocketAddress constructor in java it should be able to resolve that to one of the IP's in A records because DNS by default implements round robin as far as I know. please correct me if I am wrong.

Thanks,

Kant

Actually I had to implement resolving the DNS Names on my own. SRV-Records only point to the certain hosts. 

Thanks for your support.
