Sergey Naumov created CASSANDRA-5470:
----------------------------------------
Summary: Query with condition on two secondary indexes can't be
run without ALLOW FILTERING.
Key: CASSANDRA-5470
URL: https://issues.apache.org/jira/browse/CASSANDRA-5470
Project: Cassandra
Issue Type: Bug
Affects Versions: 1.2.3
Environment: Apache Cassandra 1.2.3 installed from DataStax debian
repository.
Reporter: Sergey Naumov
While manual explicitly suggests to use multiple secondary indices
(http://www.datastax.com/docs/1.2/ddl/indexes - Using multiple secondary
indexes), it is impossible to call such a query without ALLOW FILTERING clause.
I have the following table:
cqlsh <<SQL
DROP TABLE k1.tbl1;
CREATE TABLE k1.tbl1 (
id timeuuid,
name varchar,
regid int,
date timestamp,
time timestamp,
payload varchar,
PRIMARY KEY (id)
);
CREATE INDEX tbl1_name
ON k1.tbl1 (name);
CREATE INDEX tbl1_regid
ON k1.tbl1 (regid);
CREATE INDEX tbl1_date
ON k1.tbl1 (date);
SQL
But when I'm trying to perform a query, error occured:
cqlsh> select * from k1.tbl1 where regid = 2 and name = 'DB49';
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
Perhaps you meant to use CQL 2? Try using the -2 option when starting cqlsh.
With ALLOW FILTERING clause everything is OK.
