Sylvain Lebresne updated CASSANDRA-8424:
----------------------------------------
Issue Type: Improvement (was: Bug)
> Collection filtering not working when using PK
> ----------------------------------------------
>
> Key: CASSANDRA-8424
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8424
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Environment: [cqlsh 5.0.1 | Cassandra 2.1.2 | CQL spec 3.2.0 | Native
> protocol v3]
> Ubuntu 14.04.5 64-bit
> Reporter: Lex Lythius
> Assignee: Benjamin Lerer
> Priority: Minor
> Labels: collections
> Fix For: 2.1.3
>
>
> I can do queries for collection keys/values as detailed in
> http://www.datastax.com/dev/blog/cql-in-2-1 without problems. Even without
> having a secondary index on the collection it will work (with {{ALLOW
> FILTERING}}) but only as long as the query is performed through a *secondary*
> index. If you go through PK it won't. Of course full-scan filtering query is
> not allowed.
> As an example, I created this table:
> {code:SQL}
> CREATE TABLE test.uloc9 (
> usr int,
> type int,
> gb ascii,
> gb_q ascii,
> info map<ascii, text>,
> lat float,
> lng float,
> q int,
> traits set<ascii>,
> ts timestamp,
> PRIMARY KEY (usr, type)
> );
> CREATE INDEX uloc9_gb ON test.uloc9 (gb);
> CREATE INDEX uloc9_gb_q ON test.uloc9 (gb_q);
> CREATE INDEX uloc9_traits ON test.uloc9 (traits);
> {code}
> then added some data and queried:
> {code}
> cqlsh:test> select * from uloc9 where gb='/nw' and info contains 'argentina'
> allow filtering;
> usr | type | gb | gb_q | info | lat
> | lng | q | traits | ts
> -----+------+-----+-------+------------------------------------------+--------------+--------------+---+--------------------+--------------------------
> 1 | 0 | /nw | /nw:1 | {'ci': 'san antonio', 'co': 'argentina'} |
> -40.74000168 | -65.80000305 | 1 | {'r:photographer'} | 2014-11-04
> 18:20:29-0300
> 1 | 1 | /nw | /nw:1 | {'ci': 'san antonio', 'co': 'argentina'} |
> -40.75799942 | -66.00800323 | 1 | {'r:photographer'} | 2014-11-04
> 18:20:29-0300
> (2 rows)
> cqlsh:test> select * from uloc9 where usr=1 and info contains 'argentina'
> allow filtering;
> code=2200 [Invalid query] message="No indexed columns present in by-columns
> clause with Equal operator"
> cqlsh:test> select * from uloc9 where usr=1 and type=0 and info contains
> 'argentina' allow filtering;
> code=2200 [Invalid query] message="No indexed columns present in by-columns
> clause with Equal operator"
> {code}
> Maybe I got things wrong, but I don't see any reasons why collection
> filtering should fail when using PK while it succeeds using any secondary
> index (related or otherwise).
