Murmur3 Hash Algorithm Used in Kassandra

Question

I am trying to reproduce the Murmur3 hash in Kassandra. Does anyone know how to get the actual hash values ​​used in string keys? I just need a pair of hash values ​​from my data to verify the hash implementation is correct.

Ask Cassandra! Insert some data into the table. Subsequently, you can use the token function in the select query to get the token values ​​used. For instance:

select token(id), id from myTable; 

The cumulative key of the section is serialized as an n-fold array of bytes (which is always added with a brief indication of its length) containing the serialized value of your key element and a closure of 0. I do not understand what these closing zeros are for. Something related to SuperColumns ...
