you're overcomplicating things. just connect to *a* node, and if it happens to be down, try a different one.
nodes being down should be a rare event, not a normal condition. no need to optimize for it so much. also see http://wiki.apache.org/cassandra/FAQ#node_clients_connect_to 2010/6/1 Patricio Echagüe <patric...@gmail.com>: > Hi all, I'm using Hector framework to interact with Cassandra and at trying > to handle failover more effectively I found it a bit complicated to fetch > all cassandra nodes that are up and running. > > My goal is to keep an up-to-date list of active/up Cassandra servers to > provide HEctor every time I need to execute against the db. > > I've seen this Thrift method: get_string_property("token map") but it > returns the nodes in the ring no matter is the node is down. > > > > Any advice? > > -- > Patricio.- > -- Jonathan Ellis Project Chair, Apache Cassandra co-founder of Riptano, the source for professional Cassandra support http://riptano.com
