Using cassandra-stress to benchmark ScyllaDB 5.0.

Is there any support to limit number of items in the list?

CREATE TABLE keyspace1.users (  
username text,  
user\_fav\_movies list,  
PRIMARY KEY (username)

Cassandra-stress table user profile:

- name: user\_fav\_movies  
size: fixed(10)  
)

I think this might be what you are looking for:

```auto
  - name: user_fav_movies
    size: fixed(10)
    population: uniform(1..10000)

```
