Works great, thank you!

Hi,

How about taking it from the BoundStatement directly?

ByteBuffer routingKey = 
b.getRoutingKey(ProtocolVersion.NEWEST_SUPPORTED, codecRegistry);
Token token = metadata.newToken(routingKey);

In this case the b is the "BoundStatement". Replace codecRegistry & 
ProtocolVersion with what you have. codecRegistry for example from the 
codecRegistry = session.getCluster().getConfiguration().getCodecRegistry();

Hi,

How about taking it from the BoundStatement directly?

ByteBuffer routingKey = 
b.getRoutingKey(ProtocolVersion.NEWEST_SUPPORTED, codecRegistry);

Token token = metadata.newToken(routingKey);

In this case the b is the "BoundStatement". Replace codecRegistry & 
ProtocolVersion with what you have. codecRegistry for example from the 
codecRegistry = session.getCluster().getConfiguration().getCodecRegistry();

For partition key made of one column I use 
cluster.getMetadata().newToken(newBuffer);


But what if my key looks like this PRIMARY KEY 
((parentResourceId,timeRT), childName)?


I read that “:” is a separator but it doesn’t seem to be the case.

How can I create ByteBuffer with multiple values so that the token 
would be actually correct?


Thank you,
