Carl Yeksigian resolved CASSANDRA-10910.
----------------------------------------
    Resolution: Fixed

Actually, since there has been a fix released for the more basic issue (this one isn't as easily reproducible), let's create a new ticket to track it.

> 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?
