Lex Lythius updated CASSANDRA-8424: ----------------------------------- Labels: collections (was: ) > Collection filtering not working when using PK > ---------------------------------------------- > > Key: CASSANDRA-8424 > URL: https://issues.apache.org/jira/browse/CASSANDRA-8424 > Project: Cassandra > Issue Type: Bug > 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 > 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). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
