Take a look at your particular implementation of org.apache.cassandra.dht.IPartitioner: each partitioner: creates tokens in a different way, but all of them are straightforward.

Subject: How can the cassandra token of a key be determined from the cassandra client side?
To: <user@cassandra.apache.org>

This question relates to a C++ client application, to direct the Cassandra request to the correct Cassandra node based on token form of the key.

 

Would the following work? If the token form of the key could be determined – the keyspace description could be used to select the correct Cassandra node to which to send the request.

 

First problem is how to determine the token from the key in C++.

 

Thanks much
