I'd like some information about how secondary indices work under the hood.

1) Is data stored in some external data structure, or is it stored in an
actual Cassandra table, as columns within column families?
2) Is data stored sorted or not? How is it partitioned?
3) How can I access index data?

Thanks in a advance,
