-----------------------------------------------------------------
After reviewing [https://issues.apache.org/jira/browse/CASSANDRA-7396] in more
details and finding common grounds with that ticket, we need to allow
{{SELECT}} , {{UPDATE}}and {{DELETE}} for individual fields of the nested
collections (up to the deepest nesting level for maps, none for lists and
sets), with syntax similar to 7396. Otherwise there's no big difference between
frozen and non-frozen collections.
At this particular moment I'm not entirely certain about the slices of keys for
maps. It seems that there are many more cases for fetching a particular key
from the map by path than for slices.
