Subject [jira] [Commented] (CASSANDRA-7826) support non-frozen, nested collections

Alex Petrov commented on CASSANDRA-7826:
----------------------------------------

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}}ing, {{UPDATE}}ing and
{{DELETE}}ing 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.

> The inability to nest collections is one of the bigger data modelling limitations we
have right now.
