Paging through unordered partitioner results
When using the RandomPartitioner or Murmur3Partitioner, Cassandra rows are ordered by the hash of their value and hence the order of rows is not meaningful. Using CQL, you can page through rows even when using the random partitioner or the murmur3 partitioner using the token function as shown in this example:
SELECT * FROM test WHERE token(k) > token(42);
The ByteOrdered partitioner arranges tokens the same way as key values, but the RandomPartitioner and Murmur3Partitioner distribute tokens in a completely unordered manner. The token function makes it possible to page through these unordered partitioner results. Using the token function actually queries results directly using tokens. Underneath, the token function makes token-based comparisons and does not convert keys to tokens (not k > 42).
You can use the TOKEN function to express a conditional relation on a partition key column. In this case, the query returns rows based on the token of the partition key rather than on the value.
