Another thing to keep in mind when doing this with CQL is to take into
account the ordering partitioner you may or may not be using. If you're
using one you'll need to make sure that if you have a larger number of rows
for the partitioner key than your query limit, then you can end up in a
situati
You can iterate over them, just make sure to set a sensible row count to chunk
things up.

You can also break up the processing so only one worker reads the token ranges
for a node. That allows you to

Iterating through lots of records is not a primary use of my data.
However, there are a number scenarios where scanning the entire contents
of a column family is an interesting and useful exercise. Here are a few:
removal of orphaned records, checking the integrity a data set, and
analytics.
