Subject [jira] [Updated] (CASSANDRA-10910) Materialized view remained rows
Date Mon, 21 Dec 2015 13:14:46 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-10910?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Gábor Auth updated CASSANDRA-10910:
-----------------------------------
    Description: 
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?

It is a bug?
