Venkata Harikrishna Nukala commented on CASSANDRA-14344:
--------------------------------------------------------
I am working on code changes. Just want to check if it is expected to support
multi-column IN restriction too on clustering keys. For example:
Table:
{code:java}
CREATE TABLE ks1.t3 (
key int,
col1 int,
col2 int,
col3 int,
value int,
PRIMARY KEY (key, col1, col2, col3)
) WITH CLUSTERING ORDER BY (col1 ASC, col2 ASC, col3 ASC);
{code}
Data:
{code:java}
key | col1 | col2 | col3 | value
-----+------+------+------+-------
100 | 0 | 0 | 0 | 1
102 | 0 | 1 | 0 | 3
101 | 0 | 0 | 1 | 2
103 | 0 | 1 | 1 | 4
{code}
Query:
{code:java}
select * from ks1.t3 where (col2, col3) IN ((1,0), (1,1)) ALLOW FILTERING;
{code}
> Support the IN restrictions on indexed columns

> cqlsh:ks1> select * from t1 where key = 1 and col2 in (1) allow filtering;
>
> key | col1 | col2 | value
> -----+------+------+-------
> 1 | 1 | 1 | 1
> 1 | 2 | 1 | 3
>
> (2 rows)
> cqlsh:ks1> select * from t1 where key = 1 and col2 in (1, 2) allow filtering;
> *{color:#ff0000}InvalidRequest: Error from server: code=2200 [Invalid query]
> message="IN restrictions are not supported on indexed columns"{color}*
> cqlsh:ks1>
