[jira] [Created] (CASSANDRA-5854) SELECT with WHERE condition on
primary-key secondary-index caused rpc_timeout
Le Duc Duy created CASSANDRA-5854:
-------------------------------------
Summary: SELECT with WHERE condition on primary-key secondary-index caused rpc_timeout
Key: CASSANDRA-5854
URL: https://issues.apache.org/jira/browse/CASSANDRA-5854
Project: Cassandra
Issue Type: Bug
Components: API, Core
Affects Versions: 2.0 beta 2
Environment: [cqlsh 4.0.0 | Cassandra 2.0.0-beta2 | CQL spec 3.1.0 | Thrift protocol 19.37.0]
Ubuntu 12 lts
Reporter: Le Duc Duy
I'm trying to use new feature in cql 3.1 (create secondary index on primary key)
Following cql will reproduce the rpc_timeout bug. I included the response for your convenience
cqlsh> create KEYSPACE gurugara WITH replication = {'class': 'SimpleStrategy', 'replication_factor': 1};
cqlsh> create table Gurugara.incoming_edge (dest_id bigint, source_id bigint, type ascii, time_id timestamp, PRIMARY KEY (dest_id,time_id,source_id)) WITH CLUSTERING ORDER BY (time_id DESC);
cqlsh> CREATE INDEX incoming_edge_source_id ON gurugara.incoming_edge ( source_id );
cqlsh> SELECT time_id FROM gurugara.incoming_edge WHERE source_id = 1 AND dest_id = 2 AND type = 'like';
Bad Request: Cannot execute this query as it might involve data filtering and thus may have unpredictable performance. If you want to execute this query despite the performance unpredictability, use ALLOW FILTERING
cqlsh> SELECT time_id FROM gurugara.incoming_edge WHERE source_id = 1 AND dest_id = 2 AND type = 'like' ALLOW FILTERING;
Request did not complete within rpc_timeout.
cqlsh> INSERT INTO gurugara.incoming_edge (dest_id, time_id , source_id , type ) VALUES ( 1,2,3,'see');
cqlsh> SELECT time_id FROM gurugara.incoming_edge WHERE source_id = 1 AND dest_id = 2 AND type = 'like' ALLOW FILTERING;
Request did not complete within rpc_timeout.
cqlsh> SELECT time_id FROM gurugara.incoming_edge WHERE source_id = 3 AND dest_id = 1 AND type = 'see' ALLOW FILTERING;
Request did not complete within rpc_timeout.
