Re: Composite partition key token


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,

I would like to ask how to calculate token for composite partition key using java api?

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,

Branislav
