Description

Here is the current behavior:

cqlsh:default> create table counter_table ( i int PRIMARY KEY, j vector<counter,2> );

cqlsh:default> insert into counter_table (i, j) values (0, [0,0]);
cqlsh:default> select * from counter_table;

 i | j
---+----------------------------------------
 0 | [576460752303423488, 2251799813685248]

(1 rows) 

 We may want vectors to handle `counter` subtype as other collections do, which is throwing an error:

cqlsh:cycling>  create table upcoming_calendar ( year int, month int, events list<counter>, primary key (year, month));
InvalidRequest: Error from server: code=2200 [Invalid query] message="Counters are not allowed inside collections: list<counter>"


cqlsh:cycling>  create table upcoming_calendar ( year int, month int, events map<int, counter>, primary key (year, month));
InvalidRequest: Error from server: code=2200 [Invalid query] message="Counters are not allowed inside collections: map<int, counter>"
