[jira] [Created] (CASSANDRA-10958) Range query using secondary
index returns weird results
Taiyuan Zhang created CASSANDRA-10958:
-----------------------------------------
Summary: Range query using secondary index returns weird results
Key: CASSANDRA-10958
URL: https://issues.apache.org/jira/browse/CASSANDRA-10958
Project: Cassandra
Issue Type: Bug
Reporter: Taiyuan Zhang
Priority: Minor
I'm playing with Cassandra 3. I added a secondary index on a column of integer, then I want to do a range query. First it threw an error:
InvalidRequest: code=2200 [Invalid query] message="No supported secondary index found for the non primary key columns restrictions"
So I added 'Allow Filtering'
cqlsh:mykeyspace> SELECT * FROM test ;
id | id2 | age | extra
----+-----+-----+-------
1 | 1 | 1 | 1
2 | 2 | 2 | 2
(2 rows)
cqlsh:mykeyspace > CREATE INDEX test_age on test (extra) ;
cqlsh:mykeyspace > select * FROM test WHERE extra < 2 ALLOW FILTERING ;
id | id2 | age | extra
----+------+-----+-------
1 | 1 | 1 | 1
2 | null | 2 | null
(2 rows)
My schema is:
CREATE TABLE mykeyspace.test (
id int,
id2 int,
age int static,
extra int,
PRIMARY KEY (id, id2)
)
It certainly looks like a BUG to me, even though it has a chance to be something by-design.
