[jira] [Commented] (CASSANDRA-10910) Materialized view remained
rows
[ https://issues.apache.org/jira/browse/CASSANDRA-10910?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15081484#comment-15081484 ]
T Jake Luciani commented on CASSANDRA-10910:
--------------------------------------------
I'm wondering how this will affect the shadowable tombstone logic. Can you modify that dtest to include this update?

> Key: CASSANDRA-10910
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10910
> Project: Cassandra
> Issue Type: Bug
> Environment: Cassandra 3.0.0
> Reporter: Gábor Auth
> Assignee: Carl Yeksigian
> Fix For: 3.0.x, 3.x
>
>
> I've created a table and a materialized view.
> {code}
> > CREATE TABLE test (id text PRIMARY KEY, key text, value int);
> > CREATE MATERIALIZED VIEW test_view AS SELECT * FROM test WHERE key IS NOT NULL PRIMARY KEY(key, id);
> {code}
> I've put a value into the table:
> {code}
> > update test set key='key', value=1 where id='id';
> > select * from test; select * from test_view ;
> id | key | value
> ----+-----+-------
> id | key | 1
> (1 rows)
> key | id | value
> -----+----+-------
> key | id | 1
> (1 rows)
> {code}
> I've updated the value without specified the key of the materialized view:
> {code}
> > update test set value=2 where id='id';
> > select * from test; select * from test_view ;
> id | key | value
> ----+-----+-------
> id | key | 2
> (1 rows)
> key | id | value
> -----+----+-------
> key | id | 2
> (1 rows)
> {code}
> It works as I think...
> ...but I've updated the key of the materialized view:
> {code}
> > update test set key='newKey' where id='id';
> > select * from test; select * from test_view ;
> id | key | value
> ----+--------+-------
> id | newKey | 2
> (1 rows)
> key | id | value
> --------+----+-------
> key | id | 2
> newKey | id | 2
> (2 rows)
> {code}
> ...I've updated the value of the row:
> {code}
> > update test set key='newKey', value=3 where id='id';
> > select * from test; select * from test_view ;
> id | key | value
> ----+--------+-------
> id | newKey | 3
> (1 rows)
> key | id | value
> --------+----+-------
> key | id | 2
> newKey | id | 3
> (2 rows)
> {code}
> ...I've deleted the row by the id key:
> {code}
> > delete from test where id='id';
> > select * from test; select * from test_view ;
> id | key | value
> ----+-----+-------
> (0 rows)
> key | id | value
> -----+----+-------
> key | id | 2
> (1 rows)
> {code}
> Is it a bug?
