Gábor Auth created CASSANDRA-10910:
--------------------------------------
Summary: Materialized view remained rows
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
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)
> 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}
It is a bug?
