---------------------------------------------
Summary: Counters are erroneously allowed as map key type
Key: CASSANDRA-10760
URL: https://issues.apache.org/jira/browse/CASSANDRA-10760
Project: Cassandra
Issue Type: Bug
Components: CQL
Reporter: Aleksey Yeschenko
Priority: Minor
Fix For: 2.1.x, 2.2.x, 3.0.x
We do validate collection value types, but not collection key types, which
allows counters to be used as map keys:
{noformat}
cqlsh> create keyspace test with replication = {'class': 'SimpleStrategy',
'replication_factor': 1};
cqlsh> use test;
cqlsh:test> create table test.test (id int primary key, amap map<counter,
text>);
cqlsh:test> insert into test.test (id, amap) values (0, {1: '2'});
cqlsh:test> select * from test.test;
id | amap
----+----------
0 | {1: '2'}
(1 rows)
{noformat}
This should obviously not be allowed and must be rejected.
