I've seen in several places the advice to use queries like to this page through lots of rows:
select id from mytable where token(id) > token(last_id)
But it's hard to find detailed information about how this works (at least that I can understand -- the description in the Cassandra manual is pretty brief).
One thing I'd like to know is if new rows are always guaranteed to have token(new_id) > token(ids-of-all-previous-rows)? E.g. if I have one process that adds rows to a table, and another that processes rows from the table, can the "processor" save the id of the last row processed and when he wakes up use:
select * from mytable where token(id) > token(last_processed_id)
to process only new rows? Will this always work to get only new rows?
