Semantic Implementation(12988)
> Duplicate results with secondary index on static column
> -------------------------------------------------------
>
> Key: CASSANDRA-13277
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13277
> Project: Cassandra
> Issue Type: Bug
> Components: Feature/2i Index, Legacy/Local Write-Read Paths
> Reporter: Romain Hardouin
> Assignee: Andres de la Peña
> Priority: Normal
> Labels: 2i
> Fix For: 3.11.0, 4.0
>
>
> As a follow up of
> http://www.mail-archive.com/user@cassandra.apache.org/msg50816.html
> Duplicate results appear with secondary index on static column with RF > 1.
> Number of results vary depending on consistency level.
> Here is a CCM session to reproduce the issue:
> {code}
> romain@debian:~$ ccm create 39 -n 3 -v 3.9 -s
> Current cluster is now: 39
> romain@debian:~$ ccm node1 cqlsh
> Connected to 39 at 127.0.0.1:9042.
> [cqlsh 5.0.1 | Cassandra 3.9 | CQL spec 3.4.2 | Native protocol v4]
> Use HELP for help.
> cqlsh> CREATE KEYSPACE test WITH replication = {'class': 'SimpleStrategy',
> 'replication_factor': 2};
> cqlsh> CREATE TABLE test.idx_static (id text, id2 bigint static, added
> timestamp, source text static, dest text, primary key (id, added));
> cqlsh> CREATE index ON test.idx_static (id2);
> cqlsh> INSERT INTO test.idx_static (id, id2, added, source, dest) values
> ('id1', 22,'2017-01-28', 'src1', 'dst1');
> cqlsh> SELECT * FROM test.idx_static where id2=22;
> id | added | id2 | source | dest
> -----+---------------------------------+-----+--------+------
> id1 | 2017-01-27 23:00:00.000000+0000 | 22 | src1 | dst1
> id1 | 2017-01-27 23:00:00.000000+0000 | 22 | src1 | dst1
> (2 rows)
> cqlsh> CONSISTENCY ALL
> Consistency level set to ALL.
> cqlsh> SELECT * FROM test.idx_static where id2=22;
> id | added | id2 | source | dest
> -----+---------------------------------+-----+--------+------
> id1 | 2017-01-27 23:00:00.000000+0000 | 22 | src1 | dst1
> id1 | 2017-01-27 23:00:00.000000+0000 | 22 | src1 | dst1
> id1 | 2017-01-27 23:00:00.000000+0000 | 22 | src1 | dst1
> (3 rows)
> {code}
> When RF matches the number of nodes, it works as expected.
> Example with RF=3 and 3 nodes:
