Subject [jira] [Commented] (CASSANDRA-9838) Unable to update an element in a static list
Date Tue, 08 Sep 2015 19:02:46 GMT


Benjamin Lerer commented on CASSANDRA-9838:

Thanks for the patch. It looks good.

I just have the following comments:
* It will be nice if you could add a unit test to {{CollectionTest}} to check the behavior.
* Can you provide another patch for the 3.0 branch as this one will not apply there?

I also have a small nit:
* The {{final}} keyword can be removed. In the C* code base it is usually not used for variables.

> I created a table in cassandra  (my_table) which has a static list column sizes_list.

> I created a new row and initialized the list sizes_list as having one element. 
> {{UPDATE my_table SET sizes_list = sizes_list + [0] WHERE view_id = 0x01}}
> Now I m trying to update the element at index '0' with a statement like this
> {code}insert into my_table (my_id, is_deleted , col_id1, col_id2) values (0x01, False,
0x00, 0x00);
> UPDATE my_table SET sizes_list[0] = 100 WHERE my_id = 0x01 ;
> {code}
> Now I see an error like this: 
> {{InvalidRequest: code=2200 [Invalid query] message="List index 0 out of bound, list
has size 0"}}
> If I change my list to a non-static list, it works fine!
