Summary: SASI： Cant retrieve the result when the condition is
Mixed query condition when one conditon is "=" for a int type and other
condition is ">" for a string type
Key: CASSANDRA-15180
URL: https://issues.apache.org/jira/browse/CASSANDRA-15180
Project: Cassandra
Issue Type: Bug
Reporter: wu taiyin
I have a SASI scene and I am not sure if this is a problem.
I also create two SASI indexes for two column in one table, One column is int
type and one is text type.
When i use the query condition by these two index cloumn with ununequal
conditon , the result cannot be retrieved.
and the schema and query cql as follow :
1: create a table and SASI index for two column:
cassandra@cqlsh:app105> CREATE TABLE app105.complextestff(
... a int,
... b int,
... c int,
... d text,
... PRIMARY KEY (a,b)
... );
cassandra@cqlsh:app105> CREATE CUSTOM INDEX sasi_105_findtest4_c ON
app105.complextestff (c) USING 'org.apache.cassandra.index.sasi.SASIIndex';
cassandra@cqlsh:app105> CREATE CUSTOM INDEX sasi_105_findtest4_d ON
app105.complextestff (d) USING 'org.apache.cassandra.index.sasi.SASIIndex';
2: insert some data to this table
cassandra@cqlsh:app105> INSERT INTO complextestff(a , b , c , d ) VALUES (
1,1,1,'1');
cassandra@cqlsh:app105> INSERT INTO complextestff(a , b , c , d ) VALUES (
1,2,1,'1');
cassandra@cqlsh:app105> INSERT INTO complextestff(a , b , c , d ) VALUES (
1,3,1,'2');
cassandra@cqlsh:app105> INSERT INTO complextestff(a , b , c , d ) VALUES (
1,4,1,'2');
cassandra@cqlsh:app105> select * from complextestff ;
a | b | c | d
---+---+---+---
1 | 1 | 1 | 1
1 | 2 | 1 | 1
1 | 3 | 1 | 2
1 | 4 | 1 | 2
3: query by condition. all the index column use "=" , and it can retrieve the
result succefully.
cassandra@cqlsh:app105> select * from complextestff WHERE a=1 and c=1;
a | b | c | d
---+---+---+---
1 | 1 | 1 | 1
1 | 2 | 1 | 1
1 | 3 | 1 | 2
1 | 4 | 1 | 2
4、but when i use the ">" operator to a index column which is text type , it
cant retrieve the result succefully
cassandra@cqlsh:app105> select * from complextestff WHERE a=1 and c=1 and d >=
'1' ALLOW FILTERING;
a | b | c | d
---+---+---+---
